This is such a salient point, and always draws me back towards a desire 
for accompanying questions. They wouldn't directly address exactly the 
issue handled by ANAME (the addresses of one host corresponding to those 
of a distinct [probably out-of-bailiwick] name), but might make it 
moot—or at least tolerable—by tackling more fundamental progress 
blockers. Support for covering apex A, apex AAAA, and service-specific 
SRV (especially with target host addresses in the additional section of 
the response) in a single transaction could absolve many sins.
