It is the only way to let the user (opposed to library developers)
decide whether weak or strict type checking should be applied.

Basically, that is how strict typing works.

Well, you'll want to consider the background.  "Everybody" wanted scalar
type hints, but no broad consensus could be achieved regarding the
semantics (strict vs. weak).  The Scalar Type Declarations RFC is a
compromise trying to satisfy most developers.

Apparently, you're in favor of strict type hints, but I am not, because
it would be a pretty big change in how PHP works, and also there are
some weird edge cases, e.g.:

    <?php
    declare(strict_types=1);
    $num = 1 << 32;
    $num *= $num;
    echo dechex($num);

What's the output?
