By adding a proper tag you :

1) Assert you did a research in git history/blame to find original
commit.

2) You looked at other similar bugs added by this commit

3) Add meta information in git history to ease backports

4) CC original author to let him/her know he made a mistake and increase
his/her knowledge.

5) Help maintainers
