The current beharviour makes sense to me, if the caller don't know the
concept of strict types he must not be forced to handle it. I don't know
such examples where would be useful the callee emulate both signatures, can
you provide some? Something like correctly cast to the correct type? That
can make sense. But restrict the caller doesn't seems very valuable.

Expose only through `run-tests.php` is safer for sure, it will not be
highlighted like other constants because `zend_highlight.c` wasn't modified
but whatever, it's only for tests.
