I'm not sure about that.
In general, it's often easier to express a simple concept in
terms of a complex one than the complex concept in terms of
the simple one.
So, if you are correct (and you might be -- I've not thought
much about the implementation issues surrounding C.), I think
you should develop a better argument.
Also note that you might not need C. at all, to implement P

Using J601ibeta:
P=:1 :'(a.,~;1&|.&.>m) {~ (a.,~;m) i. ]'
