The specific-answer tag seems to contain questions only about Stack Overflow.
I did not go through all 108 questions, but quite a few of them.
I presume the tag is from when MSE was also MSO, to separate MSO questions from MSE ones.
The tag's excerpt (before the edit today) backs this up:
Use this tag for questions on Meta that relate to a specific answer on Stack Overflow.
(Edit: Note, the excerpt has just been changed "Stack Exchange")
If burnination is to proceed, how would it be done?
Just removing the tag from all questions in this case leaves off-topic questions.
Is it possible for someone to mass migrate?
Or, should we just close them all as "pertains to specific site"?
