I don't want to go off-topic but i have an important question. Isn't
a socket a concept that translates an address and port? How would
someone go about doing tcp/udp without sockets when they both depend
on address/port mappings which are _literally_ sockets?

I don't really understand your question nor where did the concept of
doing tcp/udp without sockets originated.

Maybe you're misreading the term Unix sockets? Sockets can belong to
different protocol families: INET, INET6, UNIX/LOCAL, X25, etc..

Unix sockets means using sockets for local interprocess communication.
They don't use any network protocol.
