I'd regard our primary discussion on this topic at Should we tag questions with a SharePoint version?Should we tag questions with a SharePoint version? and don't have anything further to add than my answermy answer and edit 2edit 2 there.
On second thoughts, one thing I'd like to comment on is how this situation was handled. I accept that the Stack Exchange team has experience on this topic, and perhaps our community has made the wrong choices here. However making significant changes to data and how the site is run without any consultation or warning - especially when we've discussed it more than any other meta topic (probably) - has been a disempowering experience.
