I feel like this thread has gotten somewhat side-tracked by the valid discussion about whether we should have remote tracking tags, but the much easier thing to fix is that the "+" prefix for refs/tags/* means nothing.

I noticed this when working on fetch.pruneTags in the last release, but didn't dig further.

I.e. if you clone git.git and update "master" and a tag:
$ git fetch origin 'refs/heads/*:refs/heads/*' --dry-run
From github.com:git/git
 ! [rejected]              master     -> master  (non-fast-forward)
$ git fetch origin '+refs/heads/*:refs/heads/*' --dry-run
From github.com:git/git
 + 969e05fae2...1f1cddd558 master     -> master  (forced update)
Here "+" does the right thing, but then:
$ git fetch origin 'refs/tags/*:refs/tags/*' --dry-run
From github.com:git/git
 t [tag update]            v2.17.0    -> v2.17.0
$ git fetch origin '+refs/tags/*:refs/tags/*' --dry-run
From github.com:git/git
 t [tag update]            v2.17.0    -> v2.17.0
Here the former shouldn't be clobbering the existing tag.
