First, let me be clear -- I am absolutely no fan of version tags. I think they're so dangerous that I am on the verge of banning them from the network on all SE 2.0 sites:
However, I do support version tags existing in the rare event that a question asker can make a legitimate case that their question is in fact specific to a version.
What I object to is the institutionalization of such tags, and the bogus 'requirement' that all new questions have a version tag. This is toxic. But the tags can exist.
So. Do you really want us to blacklist …
as a tag?
Are you OK with this?
