Right.

(And the reason is, there will be many such redirection sockets /
services. Many ports will not be used ever by lots of users. This saves
some RAM and perhaps boot speed. Also reduces noise from 'ps' (not loads
of duplicate systemd-socket-proxyd processes). Apparently '.socket'
files, systemd socket activation and systemd-socket-proxyd is fast. No
noticeable performance penalty in this use case.)

I see!

Thanks for the references!
