"primary" source I'd not read as the "source that's mostly asked", but in
the sense the word is used in "primary master". To comply with the above
definition, it's sufficient to supply the zone to at least one secondary
(ususally by AXFR). So even when 1035 was not explicitly designed to
support hidden primaries, it is flexible enough to allow for them.
The update to 1035 in RFC 1996 makes this even clearer.
