I agree.  We frequently reject features on the basis that someone
might do something stupid with them.  It's lame and counterproductive,
and we should stop.  The world contains infinite amounts of lameness,
but that's the world's problem, not ours.  There is zero evidence that
this feature is only useful for stupid purposes, and some evidence
(namely, the opinions of esteemed community members) that it is useful
for at least some non-stupid purposes.
