`getaddrinfo` is a POSIX function, and the POSIX specification for it[1] allows implementations that only support UDP (it even allows implementations that don't use DNS). Such implementations should (but are not required to) set the `struct addrinfo` `hints` field to `IPPROTO_UDP`. Note that POSIX only mentions "In many cases it is implemented by the Domain Name System, as documented in RFC 1034, RFC 1035, and RFC 1886." and not any later RFCs, so RFC 7766 changes aren't required for POSIX-compliant implementations.
