That is unexpected for me, since I am starting from a clean installation of
Devuan Beowulf - no upgrade, no crossover from Debian - just a totally new
install of Devuan (which I'm expecting to be ohne/sans/without systemd in any
form).

I guess I can try that, however you should be aware that when I started this
exercise (from the aforementioned fresh installation of Devuan Beowulf), the
directory /etc/udev/rules.d (a) existed and (b) was empty.

I can only say that searching /lib/udev revealed (a) nothing specific to my
network devices, and (b) no files more recent than January 1st 2020, on a
machine installed in December 2020, therefore I don't think there is anything
in there contributing to my problem.

I'll give that go tomorrow (or perhaps Tuesday; tomorrow looks like a busy
work day for me).

I shall report back.
