I've stuck to only doing this in the places where I'm sure we should never get false back. Other places I'm less sure of (and I found more bugs along the way).
when using dynamic reflection (which is the default), any time static reflection comes into play, bad shit starts to happen because of FileReadTrapStreamWrapper.
I attempted to fix these issues (phpstan/phpstan-src#801) and failed miserably.
So, to save the hassle, it's time to just remove OPcache from the picture (which, unfortunately, also means that PHPStan will not benefit from JIT).
this is not as good as phpstan/phpstan-src#769 (e.g. array_key_first()/array_key_last() aren't covered by this, nor is array_rand()) but it does eliminate the most infuriating cases where this usually crops up.
it doesn't serve any practical purpose to keep these separated, particularly since it's getting so difficult to figure out which errors are coming from which levels (since we always use 9, it doesn't really make any difference).
it's not worth this turning into compatibility baggage just so that we can parse plugin_list.yml, especially when we have new ways to handle data parsing coming in the pipeline.
For something as small as plugin_list.yml, it's easier (and in this case better too) to just validate it manually (respect/validation was anyway too strict considering it's YAML we're dealing with).
PHPStan failed on 7.4 after updating to 0.12.99, and I figured it was less hassle to just do this than fix the build. In any case, we stopped shipping 7.4 months ago, and warned at 3.22 release that 7.4 support would soon be dropped.
