I think I'd have to be playing with *several* branches simultaneously
before I got to the point of forgetting the branch name!

More to the point, your use case may be relevant for a non-bare repo
where "work" is being done, but for a bare repo on a server, I think
the branch name *does* have significance, because it's what people are
collaborating on.

(Imagine someone accidentally nukes a branch, and then someone else
tries to "git pull" and finds it gone.  Any recovery at that point
must necessarily use the branch name).
