I kinda hate to ask this question again, but are WooCommerce questions off-topic/out of scope? I try to hit the review questions whenever I visit and while the questions may be well formed and even reasonable, they seem to be Woo specific. What is the current state regarding these questions?
3rd party questions are off topic in general. WooCommerce (and Woo products in general) are 3rd party software and not automatically on topic, just because the company acquiring them just so happens to also run hosted WordPress installations as a service. As mod colleague @Tom J Nowell, who works for Automattic at the moment, pointed out, there's a difference between Automattic (the company) and WordPress(dot org, the self hosted software package).
But, in case someone can replicate an issue in a way that WooCommerce is not necessary to reproduce an issue or some custom code, it is welcome. Many third party software packages (plugins/themes) use the WP "API" anyway. The easiest way to do so is using a service like GenerateWP, mock up a quick plugin and post your question. This only includes copy-pasting the File Header, clicking together whatever you need (post types, taxonomies, etc.) and throwing your custom code on top of it.
In every other case, please do not ask questions about specific usage or implementation details of 3rd party software. As soon as plugin/theme specific hooks are in place it is impossible to test without fetching those packages. Such tasks are better kept with either the vendors support routes or just with a developer you hire and pay enough to jump on it. Or, as @birgire pointed out in the comments, you could have supported the WooCommerce.StackExchange announcement on WPTavern site.
Hope that helps.
I think what we should consider off topic and on topic should be decided by the context of the question itself. We should have some kind of grey area.
For me, the big issue with third party plugins and themes related questions are the quality of the questions. As @birgire stated, we do get quite a number of questions per day regarding Woocommerce, which should not be a real issue. The real issue is quality. Almost all questions regarding third party software are really bad quality with absolutely no context at all, almost all questions require that the reader (us) should do all the work for the person who asked the question.
I'm not attacking anyone, but most people coming here to ask questions about Woocommerce expect that we should help them regardless of their lack of effort/research or the really really poor quality of their questions. These people are the ones that want a quick fix and are really just interested in a ready-made copy/paste solution that we must provide them. These are the questions that we should close and down vote as these are the questions that does not bring any quality to the site, community or anyone else. These are the questions I consider off topic.
The very few good to excellent quality questions that we do get which are specific to third party software should be treated on merit. These are questions which are in the grey area, they are off and on topic, off topic due to their third party nature, on topic due to their good quality. I do think we have members that are prepared to invest time in answering these questions, and I'm honest in saying, if I had the knowledge, I would answer some of these questions myself.
I do feel for the very few people who really put effort into trying to solve a specific issue, then asking a question, adding all their efforts and codes, etc, just to get their questions closed with a crappy message that their efforts are off topic here. I know we should not create presidents regarding that one question is off topic and one is not, but I think we should rather reward great quality questions regardless of being third party related or not.
More than often, the people who asked these proper quality questions will come back and will eventually be a useful addition to the community. If we are going to treat their questions the same way as we do with the really poor ones, that person might never come back. People who asked poor quality questions usually never comes back anyways, or never adds anything useful to the site/community.
This is just my opinion. I really do feel questions should be treated on merit and not just the fact that they are related to third party software. I still however totally agree that generic PHP, JS and CSS related issues should be closed or moved to SO as they really do not belong here
