would be nice to have support for listening to unix sockets instead of tpc ports (reasons include, not having to dedicate a tcp port, performance, filesystem based access control~) syntax could something like this Listen unix:/tmp/nginx1.sock; (which is how nginx does it) i realize its not a much needed feature (else it'd be implemented already right?), but i need something like this right now, and Nginx has supported this for years (since 2009)
Tor recommends a unix socket configuration along with systemd's privatenetwork feature for high security: https://riseup.net/en/security/network-security/tor/onionservices-best-practices#be-careful-of-localhost-bypasses
