I suppose, in theory, a DNS query over v4 might return an AAAA

Yeah right. Try again.
Don't you have "localhost AAAA ::1" and "localhost A
127.0.0.1" configured in you DNS?
You got me there. :-)
I don't think that specific case warrants asking for AAAA records all
the time for everything even though there is no IPv6 connectivity,
though. The proper way to do this is probably to make localhost a
special case in the resolver library. This also helps avoiding
weirdness when some joker puts "localhost" with a non-localhost
address in one of your search domains.
