So here's what I'd suggest: let's define a group (my suggestion: let's
repurpose "wheel" for that) that has the effect that the passwords of

My working real-world security knowledge is dangerously out of date so I will
defer to others on the proposal itself, but: yes, we already treat wheel
membership as "able to escalate to root", and it seems sane to reuse.
Since we have group merging in effect in glibc, please do not treat a
user present in wheel group but missing in /etc/shadow as something
extra-ordinary. It is a normal situation when you have users in the
centralized identity store like FreeIPA or Samba AD.
