Comment (by PressLabs):

 I'm unsure what the stance is on the matter, but do you in core enforce
 type casting on `apply_filter` or is it too defensive and out of scope.

 I'm asking because for me it would be reasonable if I got an `int` I
 should return an `int` but in the PHP world things grow hazy on the
 matter.

 Should I cast also the `found_posts` filter a couple of lines below, as
 well?
