Dan referred me to:

It is somewhat muddy. For now, that means we are not going to overhaul
PowerDNS to comply with behaviour nobody actually uses, or can even rely on.

Normally I'm all in favour of following RFCs as closely as possible, but I
don't see a solution to this problem that does not kill our database
performance w/o overhauling our storage model.

To comply while retaining performance, we'd need to reverse our name storage
so 'www.powerdns.com' gets stored as com.powerdns.www, and we'd have to
start using 'like' queries.

Perhaps someone else, smarter than I am, can come up with a solution. As
nobody noticed our possible non-compliance for 7 years straight, I'm rather
unwilling to overhaul things as you might understand.
