What does this mean exactly? I take it you refer to the '# ethX' we add
to /etc/resolv.conf so we can remove the lines once the interface is
again down.

Did older openresolv versions not work correctly with this? E.G. is this
something that should be backported to 2019.02.x / 2019.08.x or is it
just the new version of openresolv that removes the commit? If so, how
are those lines cleaned up again?

Hello Peter

Exactly those, and similar lines (if any) in head/tail files.

Openresolv 3.9.0 and older turned "nameserver 1.2.3.4 # ethX" to
nameserver 1.2.3.4
nameserver  #
nameserver ethX

If this was broken until July this year I don't think many people are using
a
combo of udhcpc+openresolv, so I doubt that backporting is very urgent.
We need it because we have to use NetworkManager for the modem, but
we don't want NetworkManager for ethX and the rest of the system.
That's probably a pretty unique use-case.

See above. The linked mail explains in detail. The new version removes
trailing commits, and plays more nice with udhcpc.
It's just that the older versions would have extra garbage like
"nameserver #" and "nameserver ethX". Not harmful, but not useful,

All versions of openresolv are pretty good at cleaning up what is added.
There is a folder in /var/run that stores all the entries by
$interface.$type,
and those are deleted when the interface goes down. So that is fine in
all versions.
Run "resolvconf -l" to see a breakdown of all entries by origin.

Ok, does the logic in /usr/share/udhcpc/default.script to remove name
servers again when an interface is brought down then still work?

I indeed guess not.

Thanks.

Openresolv removes the comments from /etc/resolv.conf which breaks the
logic in /usr/share/udhcpc/default.script. But openresolv takes care of
that
if you add this section to a /usr/share/udhcpc/default.script.d/whatever
  deconfig)
     [ "$METHOD" = dhcp ] && /sbin/resolvconf -f -d "$interface"
     /sbin/resolvconf -f -d "$interface.$ADDRFAM"
