I would rather keep files out of the web root entirely than risk having an
executable make it 'under the wire' so to speak.  If I allow that, then
some other non-CF hack I haven't been savvy or prompt enough to patch - or
which is still unpatched - could let an attacker rename that file and
poof... An accessible executable exists whose arrival I helped facilitate.

Just last week I found some smartypants trolling my sites looking for
fckeditor's upload test page; assumedly to see if I left one of its
protocols enabled.
