> Yup—hence my suggestion to depend on “network”, which may not solve
all the problems but some—for sure. Can it cause any new problems?

Yes, because we can't bind to an interface. Network addresses change...

As for changing the documentation for Listen, quite frankly this has never
been an issue. For most users the only value they ever use is "Listen
localhost:631", which binds cupsd to the loopback interface (and in fact we
have hardcoded lookups for "localhost" to bypass common DNS issues). When
sharing is enabled we switch to "Port 631".

Using "Listen hostname" with a dynamically assigned address is just not
done...
