I understand what you're saying, and why you're saying it. But, it's
not germane to how I'm installing, much less using UUCP on macOS.
1) I'm sending UUCP traffic /through/ SSH's STDIO. The calling machine
initiates an outbound SSH connection to the called machine and launches
uucico (-r0) inside of said SSH connection. There is no need for
anything listening for TCP connections for UUCP.
2) The macOS system is initiating outbound ""calls to push and / or
pull files from the neighbor (term?) node.

I most definitely did have to re-add setuid and setgid bits.

Then it may very well be a bug.
I wouldn't be surprised to learn that I'm one of the very few people
trying to use UUCP in contemporary macOS.

I don't mind needing to /temporarily/ disable SIP. But I can see how
the need to do so is probably a bug or design flaw.
