Yes, but I can understand that they're not too inclined - I believe it's
not easy to portably get information about such RRTYPEs from the OS
resolver, e.g. I can't see a way in POSIX.  Most http libraries would
need to deal with this somehow.  It doesn't seem realistic to *wait* for
OS implementations or even APIs to improve.  Overall it seems quite a
stalemate, I'm afraid, probably without an "ideal" solution within
reasonable timeframe.
