Who knew. There are two things going on here. The first is that, unlike parse_server_name, URI.fromBytes will strip off square brackets from IPv6 literals, which means that it is valid input to ClientTLSOptionsFactory and HostnameEndpoint. The second is that we stay in `bytes` throughout (except for the argument to ClientTLSOptionsFactory), which avoids the weirdness of (sometimes) ending up with idna-encoded values being held in `unicode` variables.
