Your platform's resolver should "do the right thing" when
AddressFamily=any is in use, as this sets hints.ai_family to be
AF_UNSPEC which should be equivalent to not setting a hints (for the
common case at least). 

Perhaps your resolver is defaulting to IPv4-only lookups when no hints
is specified, but doing IPv6-then-IPv4 when hints.ai_family==AF_UNSPEC.
IMO this would be rather silly behaviour, but I have seen libc authors
do dumber things...

IIRC we need to fill out hints for either SRV RR or SCTP support, but
my memory is hazy.
