Not sure how many of you know about Psalm: https://psalm.dev/
Project lead were friendly enough to merge my PR, which will make Psalm more usable for Yii projects (since absolutely everything in Yii2 implements __call one way or the other).
The PR includes a new setting: sealAllMethods. Using this, Psalm will assume all methods are either implemented or defined with @method class annotation. Code like this will then report an error:
$query = new \yii\db\Query();
$query->undefinedmethod(); // Error: No such method
