I was initially quite confused about the proposal's first sentence: "Adding a 
property to a public struct in Swift ought to not be a source-breaking change.” 
Because I nearly always rely (like many developers) on struct automatic 
initializers, adding a property is pretty much always a source-breaking if I 
don’t write an explicit initializer with the same signature as the old 
automatic. Can something be done to clarify the proposal in that regard or is 
it too late?
