Another possibly-crazy thought ...

Should BULK be allocated from the metatype range, 128-255? The idea being
that this would cause the zone xfer to be rejected by servers that don't
understand it.

... but, from looking at BIND's code (I didn't test it) I think this idea
wouldn't actually work in practice because BIND only rejects xfers
containing explicitly-known metatypes - it treats most of 128-255 as
unknown.
