> The async/await API's and their rigid nature was torture

Way better than callback hell. The only awkwardness surrounds streams of tasks.

Operator overloading is a necessity. Matrices, big integers and so on, all require the familiar operators for clear code. Type inference is here to stay, and every new language has it. The fact that every language is also trying to adopt a streaming API like LINQ should also tell you something.

I'm afraid you're on the losing side of history on all of these points. C# does include a lot, and I would certainly prefer a single uniform abstraction to handle many things, ie. generators and async/await can be unified under coroutines or something similar, but the proliferation of "kitchen sink" features is not nearly as bad as you imply.
