Personally, I do not mind typing

find [file] [exp] -exec rm {} +

because I can give rm arguments (-i and -P mostly, though its funny to
think about using -W with find) which produce the expected behavior,
and it is a consistent form.
Is it arbitrary, a habit, or is there something else to it?  Well, I'm
all about homeostatic property clusters myself, but a metaphysical
discussion is beyond the scope of this list (I think). ;)

"The frivolity and boredom which unsettle the established order, the
vague foreboding of something unknown, these are the heralds of
approaching change.  The gradual crumbling that left unaltered the the
face of the whole is cut short by a sunburst which, in one flash,
illuminates the features of the new world."  --G.W.F. Hegel,
_Phenomenology of Spirit_ 5:11
