Should branches be objects?

[I'm a list newbie here, but a git power user.]

If branches were objects...

 - one could see the history of branches, including

 - how commits were grouped when pushed/pulled (push 5 commits, and
the branch object will record that its head moved by those five
commits at once)

 - rebase history (git log <branch-object> -> better than git reflog!)

 - object transactional APIs would be used to update branches

Branch objects might be purely local, recording what was done in a local repo to a branch, but they might be pullable, to make branch history viewable in clones.

Just a thought,
