I didn't look at the code, I knew you were right after reading your 
points. I just failed in admitting that in time.

You're being nice to Devuan here, or why are you not moving completely 
to systemd-sysusers?

It does, I think. I haven't really thought about those upgrading things, 
but I took from this discussion that preinst and postinst scripts are 
likely to run with pre-upgrader versions of adduser. That's a real pity 
since it will slow down Debian's speed to simplify maintainer scripts 
but that's just the way things are.
