The rule seems to be making a combeack since Monsters of the Multiverse with things like enemy offensive spells no longer counting as spells (and thus being uncounterable), weapon attacks dealing unusual damage types at the hands of NPCs etc.Speaking of which, that's something I find wrong with 5e: they mostly dropped the 4e philosophy that monsters don't have to follow the same design rules as players. That was one of the best features of 4e, and I miss it.
Can't say I'm a fan. It ruins the rules-fiction consistency IMO.
