It's not out of scope, because this is not a binary data format.

Saying "I intended to make a defctive thing doesn't" doesn't change the fact that it's defective.

A car without windshield wipers is defective, or at best inexcusably limited. Saying "I only designed it to use in the sun" doesn't make it suddenly perfectly useful.

If you want to try to say that json was actually intended to only be used in special conditions like an exotic car with no roof, then it's fair for everyone else to say "Ok, well that intentional design is a crap design of limited use. People actually need a car WITH windshield wipers."

The simple fact that it's a text format invalidates all the attemped arguments that it's just a machine to machine data format never intended for humans to mess with. People aren't "holding it wrong".
