Yes. OTOH maybe some "secret" testing period without a public
explanation of the new feature wouldn't hurt, either, so this may
not be so urgent.
Yes, I had in mind such a testing period before publicizing the
change.

I haven't had time to make the change yet, but it now seems to me that
"sibling" is the wrong word, since siblinghood is inherently mutual
(also transitive) and I don't have that in mind here. I'm now thinking
of "host" (or perhaps "server"). If package A specifies B as
"host"
(let's say) that gives A access to B's private functions, but not vice
versa.
I haven't even thought about multiple layers of hosting, but as things
stand the answer to the question above is No.
