OK, and I agree that if such a registry is pulled and under a clear charter
of mandating multiple technologies within an independent body then a
discussion starts to make sense and what the size of that should be given
that mandates algorithms over multiple technologies (SR, unicast, mcast,
whatever) and implies a "God's eye view" of all the elements of all the
technologies (and if a computation touches elements from two technologies
they become [optionally] coupled).  We are not talking IGP registry or
multicast computation registry or SR registry then but a "wider scope
registry". Yes, that is an intriguing thought with its own validity but
outside the scope of charter we're under as BIER.  Personally, I consider
multiple, if needed loosely coupled registries for each technology a less
centralized and hence "more Internet like" solution but I see how opinions
on such a thing can diverge ...
