Don't count on it.

Even if I did change [0] to [], I'm not going to be able to add the
"__counted_by(numEntries);" because that's just not something that our build
system uses.

And even then, I would need to change all [0] to [].

You're not going to be able to use RM's header files as-is anyway in the
long term. If we changed the layout of PACKED_REGISTRY_TABLE, we're not
going to create a PACKED_REGISTRY_TABLE2 and keep both around.  We're just
going to change PACKED_REGISTRY_TABLE and pretend the previous version never
existed. You will then have to manually copy the new struct to your header
files and and maintain two versions yourself.
