I didn't mean to imply otherwise. What I was trying to say is that it's on your 
team's radar and trying to propose it probably won't be especially helpful.

Hi Remy, Brent,

We’re thinking about it but there are no plans for Swift 3 in this respect 
(although I think we’re going to keep the NS prefix on these types).

One of the complexities with this type is its performance characteristics, 
especially when used with CoreData (the reason it was introduced). CoreData 
relies a lot on proxying for performance reasons, but there is currently an 
impedance mismatch between that behavior and Swift’s focus on static typing.

Swift Evolution proposal SE-0069 "Mutability and Foundation Value Types" notes 
at the bottom

So sit tight—the Foundation team is already thinking about this. (That doesn't 
mean you'll necessarily see it this year, though.)
