Note that even though packed-refs does not have this limitation, we
still enforce it in order to avoid headaches when moving between loose
and packed refs.

Likewise, we'll probably[1] continue to enforce it with reftables, at
least for a while, to make things less confusing when pushing and
pulling between repositories with different storage. If reftables become
the widespread default, then I imagine we'd consider loosening it then
(or alternatively, adding a config option for people who want the
flexibility and don't mind the interoperability cost).


[1] I didn't actually check what the current reftable patches do, but
    that's my recollection from discussions long ago.
