.NET has millions of developers. They optimize for the greatest impact and async is necessary for performance. In fact high-performance is an explicit goal of the framework and it ranks at the top of the TechEmpower benchmarks. Even if you don't need the performance, async code helps keep your app responsive and use less resources on your server. It's far better to have async and not need it then try to refactor your entire ap when it's necessary.
