If at all possible, permit it to also run without systemd and/or
Network-Manager in the mix, for use-cases where all the bells and whistles
(and complications, and deep integration into things it does not need to
integrate into, nor necessarily should integrate into, like SSH server)
is not required.

To have Netplan as an option (which should be the case for systemd and
Network-Manager as well, options) seems very sensible IMHO.

Question: is ifupdown-ng geared at replacing ifupdown as soon as the next
major release, and should those that today use ifupdown migrate to
ifupdown-ng proactively? And does Netplan generate ifupdown-ng
configuration, or it this strictly a helper-tool for systemd/NM?

Very glad to hear that.
