This sounds right to me too. There's nothing wrong with having a
detached HEAD, and nothing wrong with creating commits in that state.
You're effectively creating an anonymous branch in the DAG and it's
subject to garbage collection if you move away from that anonymous
branch w/o naming it.

Pedantic note: you don't lose those commits at the next checkout. They
are merely subject to garbage collection (and not until they age out
of HEAD's reflog). I know you know that, just being precise. :-)
