Agreed.

Since Swift 3.0 is a code-breaking change my guess is that there is no burden
if the Xcode migration assistent automatically changes all #if os(osx) to #if
os(macos), thus deprecating the term osx, not burdening the developer at all.

I don't see them as two different OSs, mostly since version-wise it's OS X
10.11 and macOS 10.12. It's the same OS, different name - it IMHO should be an
alias.
If iOS was renamed to phoneOS and kept versioning, you'd still expect #if
os(ios) to be matched when targetting phoneOS and vice-versa.
If you need to differentiate between versions of the OS, there are #if
available(*) "macros" or simply NSAppKitVersion constants.

Sure, but with Xcode 8 and Swift 3, the SDK will still be for macOS 10.12, so
it could simply say #if os(macos), even when targetting prior OSs.
All, of course, unless you want to apply these changes to Swift 2.x as well.
