[19:44:02] <AaronSchulz>	 Krinkle: it seems like ResourceLoader.php might benefit from using classes instead of arrays. There are lots possible array fields and array "shapes" with various "if" statements using key existence checks as a proxy for "is it this type of array?". It makes it harder to review things like https://gerrit.wikimedia.org/r/c/mediawiki/core/+/905156/23/includes/ResourceLoader/ResourceLoader.php .
