I understand exactly what you mean.  Perhaps your concern is a result of the character of many of these recent proposals: because we’re trying to get things settled for Swift 3, we’re hyper-focused on front-loading the “things we want to take away”, rather than spending time on sugar and other things that make the language feel more nice.  The rationale for this approach is sound IMO (sugar can be added at any time later) but I can understand how it would feel like we’re "taking away” without “giving anything back” in this respect.
