RFC 4703, section 5.3.1.  In order for updates to proceed, a query
on the name must be NXDOMAIN, to ensure that it has not yet been
allocated.  This is not a specific query, but rather a prerequisite
on the first update attempt.

Short of editing sources, I don't see a way.

In theory you should be able to just insert the TXT record when you
add the AAAA.  But now that I remember, I think our ddns removals will
drop the TXT record if it expired the last A record.  We should
probably be checking for both A and AAAA there.
