Yay! Why not call the feature "metazones" since that's the term we are
familiar with?

I recently hacked together a crappy version, which is deliberately dumb
and BIND-specific. http://dotat.at/prog/nsnotifyd/

I didn't implement Vixie-format metazones mainly out of laziness. My
configuration is based on named ACLs and server lists (etc.) which helps
to decouple the zone configurations from the server configurations -
addresses, TSIG keys, etc. I incorrectly thought that Vixie's format was
too address-based, but in fact I could have just left out the *.servers
sub-tree and let the metazone refer to implicit out-of-zone data. I would
have had to add an allow-query subtree too.
