I've noticed a lot of questions have been tagged trump-impeachment. The consensus, I think, used to be that separate tags should be preferred over such specific tags, for example based on these questions:
Based on that, should we rollback questions that have had such composite tags added overnight? In this case, I'm specifically asking about the trump-impeachment tag in this case.
I'm aware there's also a trump-wall tag, but that seems to be about a specific concept that's not fully captured by another combination of tags. This question isn't about that.
