Looking at the grammar -- the only downside of the current approach is that you can't do 'await await fut'. I still think that it reads better with parens. If we put 'await' to 'factor' terminal we would allow

await -fut # await (-fut)

Is there really a need to disallow that? It would take a fairly bizarre API to make it meaningful in the first place, but in any case, it's fairly clear what order of operations is intended without the parens.
