I agree with this.

We should also retain the promisor objects that are not referenced by
any other promisor object, regardless of whether it matches the filter.
(If not, the resulting repository will not pass fsck.)

The place to make this change is most likely in
repack_promisor_objects() in builtin/repack.c. Currently, it just
repacks all known promisor objects into one - modifying it to only
repack the ones we want (and adding a CLI option etc.) should be
sufficient.
