Here on Meta we have a tag limits. It doesn't come with a wiki. There are no watchers for that tag.
Looking at the 52 questions in that tag you'll find ones about question bans, input limits, voting limits, technical limits. I wouldn't say that tag will ever describe the question, except that the word by itself is part of the content of the question. That doesn't add anything you can't search for.
Asking about limits is on topic on MSE but the types of limits are broad and without context, a question tagged with only limits is missing obvious context.
I propose those 52 questions are re-tagged with their correct context tag:
For the remainder of the questions the tag should be removed.
Those actions should lead to a burnination of the tag limits.
