Trust.

None of git itself normally has any "trust". The SHA1 means that the _integrity_ of the archive is ensured, but for some things (notably releases), you want to have something else. That's the "tag object".

And I really should probably have called them something else. _I_ personally tend to want to have a 1:1 relationship between my "tag references" (ie the 20-byte SHA1 pointer) and my "tag objects", but that's because my releases are things that I envision people may actually want to verify are mine.

In many cases, you'd never use a "tag object", and the "tag reference" would just point directly to a commit, with no extra indirect object.
