It's funny you would argue that, because imho openssh would actually be
a good candidate for supporting first-class endpoints:  Doing so would
allow the user to specify whether IPv4, IPv6 or both (default) should
be allowed for connections.  For other service that support sockets as
well as TCP/IP ports, the benefit would be even greater.

I understand that copypasting all the fields into Guix records is a bit
of a non-starter, but I don't think it's a good idea to simply give up.
I just need some pointers in which direction to continue.

Cheers
