I cannot speak for StataCorp, but I think the main problem with implementing this wish-list item is how they are to define "something-nasty". And I suspect that this problem will be subtly different from one operating system to the next.

Dear list,

This hasn't been a problem yet for me, and I've heard nothing to
suggest that it has been a problem for others, but:

If someone distributes a program that includes something like

        shell do-something-nasty

will Stata do-something-nasty as the program instructs, or will it stop
and ask me for permission? (as far as I can tell, Stata will do what
the program says).

If Stata goes right ahead and does-something-nasty, then are there good
reasons not to ask for a wish-list item that might stop that from
happening without additional user input?

The manuals may well address this question; my manuals are out of reach
for now. And I haven't summoned to courage to write a test program that
tries to erase my hard disk.
