Does MyObject have an implicit decl of `new`, or are we referring to `NSObject`s `new`? Ideally we would an attribute on a particular `new` instead, but that might not work.


We're referring to NSObject's new. I don't think it's unreasonable to ask users who override init to be unavailable also override new with the same annotation, but it seems like extra boilerplate for something that we can easily infer in clang. What other consumers are you concerned about?
