As keramida has noted this particular case is more likely to be made
by mistake than many others, e.g. by doing "rm -rf / foo/bar" where
"rm -rf /foo/bar/" was meant.  Therefor I really think keramidas
_optional_ foot-shooting feature is a nice thing.

I know I will enable it on my systems if it's committed, and probably
keep it as a local patch if not.
