getaddrinfo was designed to be extensible as was struct
addrinfo. Part of the problem with TTL is not data sources
used by getaddrinfo have TTL information. Additionally for
many uses you want to reconnect to the same server rather
than the same name. Note there is nothing to prevent a
getaddrinfo implementation maintaining its own cache though
if I was implementing such a cache I would have a flag to
to force a refresh.
