Would it be possible to drop a PR comment with each change to show what PHPStan had complained about for each instance? That would help with reviewing. Basically inlining this comment: #4733 (comment).

The value that core is looking for is specifically false. While empty() will have the same effect, it will also match other falsy values. Is this needed because _WP_Dependency::$src is defined as only being a string?

Below message, I'm getting while running the phpstan.
------ -------------------------------------------------------------------------------------
Line includes/validation/class-amp-validation-callback-wrapper.php
------ -------------------------------------------------------------------------------------
326 Result of && is always false.
326 Strict comparison using === between false and string will always evaluate to false.

Yes, As per documentation in core _WP_Dependency::$src have only a string value.

Seems like that's something that WordPress core should fix in its phpdoc as well, but I don't see any downside to using empty() instead of checking for false.
