FWIW I tried to stop doing this in the actual AST representation and it caused problems (https://github.com/apple/swift/pull/8540/commits/4f6e88b009ad07edd35343c2c9b758f03029a731 <https://github.com/apple/swift/pull/8540>). That's probably the right way for us to go for real, though, not just hiding the kind in the printer.
