I don't work in C#, but I must say, these seem like great features to me, and not too crufty/bloaty at all.
Scrolling through the other recent feature additions, they all look like things that would make a language feel smoother rather than more noisy. But again, IANAC#D.
I wrote C# daily before I switched to F# ~3 years ago and I sometimes struggle reading "modern" C# code. In C# you now often have multiple ways of doing the same thing.
