People do it all the time, often unwittingly, typically by
having setuid or settgid scripts that end up invoking an
editor. I've run into the problem myself.
But I agree that this bug is not a new one. The first bug
report I could find for it was from Chris Torek, dated 1983!
I suppose that if Emacs users have lived with this security
hole for three decades, they can live with it for a while
longer. So I reverted the change from the trunk.
Here's a copy of Torek's report:
