The RFC says: "using *weak mode function parameter coercion* (stricter than traditional
casts)." (emphasis not mine) If it were to act like strict-mode arguments, it’d be more like
a type-check than a cast. The entire point of a cast is to "turn one type into another"
and strict mode doesn’t do that at all. Parameter coercion in non-strict mode (I hesitate to call
it "weak mode" because in some ways it’s stronger than strict mode) is a well-documented
behaviour, and if you’re used to working with it, this is a welcome addition, IMHO.
