Optional interface for a ResponseWriter to expose Conns

crypto/tls has let you do this since go1.18 so it doesn't seem like the worst idea (https://pkg.go.dev/crypto/tls#Conn.NetConn). Though they have the benefit of always having a TCP connection (except when using QUIC).

Out of interest, what in particular are you trying to get from the underlying connection?

So for what it's worth here's one way to slice it, although there are other ways it can be done (or with other naming)

Basically I need access to retrieve the local/remote addresses of the connections.

For more explanation: some platforms (cough, Windows, cough) do not allow you to firewall anything on localhost so if you want to perform any introspection or security controls you have to do it yourself, so having connection information is extremely useful.
