If you really don't want to, I'm not wedded to it.  It just came up on the 
other thread, and it's easy enough to throw it out there for discussion.

I don't like a million "are you really sure?!"'s from tools, but now 
and then it's nice to have a little barrier to screwup.

So, do as you like with it, I won't be offended if you don't want it.
