Right, and there is clearly no chance of it being enforced in Swift 4, so
it is either going to be unenforced and misleading, or not permitted and
not misleading.

That is totally another topic.

It clearly doesn't have any chance of implementation for Swift 4. The
proposal itself doesn't need much as it's already spelled out; it's
entirely the implementation that needs work, for which I have neither the
time nor the expertise. Since it is an additive change, though, there
really is no rush as it can be done at any time. There are just so many
other priorities.
