The question is why π is accepted but ∇ is not.

The immediate reason is that π is a letter while ∇ is not. But the
question, then, is why bother excluding nonletters from identifiers.

Personally, I don't think even π should be used in identifiers.
Mathematicians and physicists have a questionable tradition of using
single-character identifiers in their formulas. That shouldn't be
transported to programming.
