To be fair, both your examples were already taken care of.

This is not scripting.  Whether or not emacs is as restrictive as it
should be, I don't know, but there's clearly a large subset of
variables/values that can quite safely be set.

Yes, if emacs were the kernel, it would have to take a more conservative
approach -- but it's not, and convience _is_ important.

[Of course, it helps that the `local variables' section is not
interpreted for such obviously suspicious sources such as email or news,
and that emacs users are in general a more clueful lot than typical MS
product users]

Who cares about other editors?  I certainly don't.
