What? That's not the same thing at all. I'm pretty sure those functions are deprecated *because* we have array callback forms, so you can use call_user_func to call a method. PHP has a well-defined definition of "callable", as used by is_callable() and function parameter typehints, and literally everywhere that wants a callback. Since there's no such thing as a function or method pointer, that definition includes a string identifying a plain function, and two array forms, [string, string] and [object, string], representing static and instance methods, respectively. You can't not accept those forms as a callback parameter in one particular function just to make things tidier.
