I thought checking them out was the main use for tags. For example, if
I want to build version 4.9.0 of gcc, I clone their repo, check out
the gcc-4_9_0-release tag, and build. The detached state is fine since
I'm not planning to commit there. I might be using git all wrong of
course :-)

That suggests the tag is where we branched for 8.0.x though, but I
think the idea is to put the tag at the version bump, right after the
7.0.x branch point. So I don't think branchpoint is a good name -- it
seems we're already thinking it means different things :-)
