Is there a better way to express nested namespaces in C++ within the header
...at you rarely need more than two, from my experience, even on a large code base. Nesting deeper or more shallow is a tradeoff.
Now, the Microsoft case is arguably different. Presumably a much larger team, and all the code is library.
I'd assume Microsoft is imitating here the success of the .NET...

How to call asynchronous method from synchronous method in C#?
...
Asynchronous programming does "grow" through the code base. It has been compared to a zombie virus. The best solution is to allow it to grow, but sometimes that's not possible.
