Well, OK, if that's an issue you spread the names out like we did with
VBR.  If the primary is foo.com and the secondary is bar.org:

bar.org._same.foo.com. SAME .	; yes, we're a primary for whatever name that was

_same.bar.org. SAME foo.com. ; yes, we're secondary for foo.com.

This makes it somewhat more difficult to scrape all the secondaries
for a primary which may be a feature.
