Maybe, maybe not.  The number of local variables that people are
likely to set is rather limited, and the most commonly-encountered
ones are already in the default value of `safe-local-variables'.  It's
possible that a user may never be asked that question (and when we
need to ask, we should).

Still, it's not difficult to change the code so that we display all
the local variables and ask if you user wants to set them all.  I
guess the decision is up to Richard.

Sorry, you're just being a drama queen here.  The variable in question
is a whitelist of safe variables.
