The tools are a big obstacle. The industry is built around synchronous design. How are you going to time your circuit? Verify it? Etc.
It's a really big chunk of work to bite off, even with a "little" microcontroller.
We might see it one day, but as best I can tell things like sleep states are still a big focus, as they can save orders of magnitude power, instead of a few percent.
