I would like it to be integrated into the DNS server, like automatic
DNSSEC signing. But you can implement it as a bag on the side and lots of
places have already done that. (I have a half-arsed implementation which I
desperately want to replace with something better.)

It doesn't have to be sequential like that: the additional section
processing on auth and rec servers, and resolver ANAME optimization won't
cause any interop problems, so they can be deployed whenever the code is
ready and they'll have a useful effect when they encounter an ANAME
record.
