I'm sure you are ;-)

I'm not expert at all of early ObjC... But wasn't NSProxy the base of 
good-old-times RPC?

OK, in 2017 we know that RPC is dangerous. For example, when `() -> Int` relies 
on a network call, it's almost impossible to handle errors.

But still, is it because an API can be used for bad things that an API is bad?
