Please name one such method which is immediately compatible with
existing entrenched nameservers, (eg. BIND-based installs).

And keep in mind that the site installing Unbound won't likely have the
root password for the upstream master nameserver either.

NOTIFY is already in use now for very similar purposes (conceptually
speaking), and it works just fine.

Unbound already has a "zone flush" feature -- it's just a matter of glue
to make Unbound compatible with existing NOTIFY-based mechanisms.

Or would you rather also remove the zone flush feature to avoid what you
seem to be saying would be an abuse of it?

I'm just trying to get a handle on why this obvious extension of an
existing feature is being shot down without any apparent consideration
to interoperability and extension of existing features.
