Please not; screen has no business interfering with the PAM stack, it
does not start login sessions by itself.

Also, IIRC this would require root privileges, which screen usually
does not (and should not) have.

But that screen process would still be running in the user's logind
session cgroup, so logind can see that the session is still active
that way? (Unless you configured it to kill all session processes on
logout).
