If you created a table in Model on restart it would be in TempDB and in the state created. Am I reading correctly here? Then:

(1) I have a place that I can log what happened since the last restart.

(2) I can detect that a restart has happened.

Further this could lead to serious abuse.

We have been conducting interviews for new candidates. We actually give them broken code to work on and a set of bug reports. We could use this to put a copy of the tables in Model and all our data would be back to pristine on reboot. We already copy the broken code back on reboot.
