It seems to me that a simple solution to this is to default to using async for everything. That way there is no "colours", everything is a single colour (async) and everybody is happy.

Can you see a problem with this approach?

Nope! That's what Go does under the hood... and then eliminates keywords like await/yield and promises, because they're always implicitly there.

On Linux, nonblocking IO has not always been great, so under the covers Go often translates calls to actually schedule blocking work on a threadpool somewhere, but from the perspective of the programmer, everything is implicitly using await/yield and promises.
