I'm doing some updates for nodm and had a look at this bug, too.
Is this bug still relevant? I do not see any indications on
tracker.debian.org nor any related lintian problem.
Further the patch in [1] is only partially applied to gdm3 (no
relevant change in postinst compared to nodm) and it contradicts at
least 1. of the list above (it *removes* the systemd unit
Alias=display-manager.service).
I compared the postints of gdm3 and nodem and they are the same in
this regard. Further the systemd unit file of nodm does not contain
Alias=display-manager.service (so no patch needed here?).
Greetings
Helge
