WordPress questions were never declared as off topic on Stack Overflow, and there are some rules preventing migration:

• Low quality questions are closed, not migrated.
• If something could be on topic one two sites the questions stays where it was asked.
• The tag wordpress on SO isn't always used properly. Many of those questions would be off topic here (I'm following the tag).

We get already more questions than we can handle. People who prepare their questions properly will find our site anyway. Those who don't will ask on Stack Overflow. We don't need more bad questions.

In short: I see no harm. We should focus on our profile and care about off topic questions here more than on SO.
