Do you support the famous problem of resetting root's passwd in single
user mode in your scheme? In my opinion, being able to boot a rescue
cdrom and remove the root passwd on hard disk is an absolute must.
Otherwise, if the console is marked insecure you cannot enter the system
at all, and you are good for reinstall. The fallback to a small flat
passwd file in single user mode looks perfectly fine to me. Then you can
edit it with a rescue cdrom, reboot single user even on an insecure
console and do whatever necessary.
