Please do not add tags that haven't been explicitly given. If we start
assuming one another's stance about patches, the trust we can have in
these tags is significantly reduced.

Doing so also doesn't achieve anything in terms of efficiency; if I am
ok with v3 I can give my Reviewed-by on it, and the tag can be picked up
along with the patch when it is applied.
