My understanding of coloring is "needs special treatment".
Being special or not (containing an 'await' or not), as long as I don't
need to care, I can call them either way (with 'await' or not) and each
case works sensibly that's fine with me.
Sensible would be something similar to:
call function: business as usual
await function: suspension point and runs the function until completion
call awaitable: runs the awaitable until completion
await awaitable: suspension point and could be suspended internally as well
