Determine return value from `\Drupal\Core\Config\Config::get` about phpstan-drupal HOT 4 OPEN

The one hard part I foresee: I'm pretty sure the typed config manager is stateful. If it doesn't rely on the database at all and only plugin discovery maybe we can make this work

Why not contribute a method(s) to the class in Drupal that returns explicit types, and even throws an exception if the type is not a match? It seems like methods for scalar types like Config::getString() should be feasible? The caller is responsible for knowing what type to expect.

@simesy interesting idea, I just came across this in Symfony's ParameterBag class.

Just a side note, now that constraints are also applicable to config entities, we can go even crazier stuff and parse those as well and tell PHPStan that something is not string, but an enum or such.
