As a nitpick, it feels "wrong" to me to keep a decl modifier around for something that's only a compatibility feature and not natively supported. The proposal notes that a 'objcoptional' modifier was considered and rejected, but why not a single attribute, '@objcOptional' or something like that?

It shouldn't be an attribute because it changes the type signature of references to the requirement.
