Ok, I mis-interpreted your intention.

I wasn't suggesting they *should* or *should not* be foolable. I was
really trying to say that the design should not be based on whether or
not a user can *intentionally* override something - because one way or
another the user can. The design should be whatever is:
* easy to maintain
* robust in the face of usual and common-unusual conditions.
