It's not, because you would have to implement a full static analyzer that traces where the result of a `findOne` call is checked for `null` and then check that the condition always leads to a `NotFoundError`. At best you've got a linter that only works some of the time, at worst you've just made your linter terribly slow and buggy.

Except no, it isn’t, because these tools still ignore that line sometimes so I still have to check for it myself.
