[Question] What lacks in packages github.com/txthinking/socks5 and github.com/pion/dtls for working with bind-if, fwmark and upcomming xsocket options?

So, bind-if, fwmark and upcomming xsocket options cannot work if using DTLS or SOCKS5 proxies because of DTLS/SOCKS5 packages that open fd's internally.

What lacks in these packages to be compatible with these options? Functions for altering the socket created for connection(s)?
