If it waited some time for itself, then a possible difference between
PAM's waiting time and ssh's waiting time would hard to be detect,
as root may cause other waiting times than other accounts in PAM.
And I prefer, if people know that I let not ssh in, than that they
may be able to check for the root-password.

Thats why I talked about "resonable" security checks. Duplicating all
of PAM's functionality would be bloat. Disenabling possible security
problems by early disabling root seems reasonable to me.
