Given that there are some legitimate uses for such setups, I think
the ISC should consider supporting FQDNs in masters-lists, especially
since this would also add flexibility to non-dynamic setups.

In any case where the master doesn't reside in the namespace that
it provides, it would IMHO be a Good Thing to be able to refer to
it by name, since this would make the slave configuration indepandant
of master IP address changes (which I assume to be more likely /
frequent than name changes).

Agreed, but as with any other ascpect of DNS configuration, the
administrator should know what he's doing. I don't think that
just because it could be used improperly is a good reason not
to provide a certain feature.

What do you think? Should I propose this to bind-suggest at isc.org?
