Currently all plugin related questions are off-topic. But generally almost every WP developers have used plugins likes Woo-commerce, ACF.
And WP developers are most time works (Work mean not just changing setting, I am talking about development using action and filter, etc) with those plugins.
So is it a bad idea make some plugins development related question on-topic?
My suggest is starting a Meta post and allow users to upvote plugins (Like Community Promotion Ads - 2014).
If a plugin got a specific votes (just assume 15), make that plugin as on-topic...
