Just skimming and saw

Deprecate using values of type null and bool as array offsets and when calling array_key_exists()

The discussion that follows says what is wrong with null (and I agree with that), but not why bool should be deprecated as well (in fact it mentions that bool gets cast to int). It's just that I've more than once found it self-documenting to use a bool as an array offset because I wanted to partition an array into two according to a predicate - e.g., $partition[true] contains those elements that satisfy the predicate. Especially when the question of which of those two partitions I want is itself a runtime boolean decision.
