Sorry for the delay, I tried bumping the severity to buy myself some time.

It seems this is an adduser bug and the following patch fixes it:
--- adduser.orig    2018-09-15 21:12:39.000000000 +0200
+++ adduser    2022-02-10 22:27:05.759922091 +0100

     $shell = $special_shell || '/usr/sbin/nologin';
     $undouser = $new_name;
     my $useradd = &which('useradd');
-    &systemcall($useradd, '-d', $home_dir, '-g', $ingroup_name, '-s',
+    &systemcall($useradd, '-r', '-d', $home_dir, '-g', $ingroup_name, '-s',
         $shell, '-u', $new_uid, $new_name);
     if(!$disabled_login) {
         my $usermod = &which('usermod');

Apparently useradd correctly guessed system user ranges in the past,
but this is not something to rely on.

Cheers,
Balint
