Can you say more about the context?  For example, was this actually
happening, or is this for the sake of understanding the protocol
better?

I ask because knowing the context might help us give more specific
advice.

Sometimes when people delete a branch they really want those objects
to be inaccessible *right away*.  So for such people, git's behavior
of failing the request unless the objects are still accessible by
some other path is helpful.

A stateful server could theoretically cache the list of objects they
have advertised for a short time, to avoid clients having to suffer
when something becomes inaccessible during the window between the
upload-pack advertisement and upload-pack request.  Or a permissive
server can allow all wants except a specific blacklist (and some
people do that).
