I know. Check my resume, I worked at Sun, and I was literally part of that
discussion.

We decided that although you could detect someone doing something wilfully
dumb (rm -rf /) you could not, because of shell expansion, not block
something very, very similar (rm -rf /*)

We chose the mitigation to be the lightest possible block against
stupidity, akin to what Tor are doing with "you have to enable two options
to prove that you really, really mean to do this".

The OP's concerns were not frivolous.


I concur, they are not frivolous, but they were/are perceived
disproportionately, with consequent over-mitigation being proposed.

But from other posts on this thread it is obvious (IMHO) the developers

Agreed.
