> But why would we? I already have a working solution. 

I've heard some complaints that it's hard to migrate to Python 3.7 because async and await are keywords (although I think by now all popular libraries have migrated already), so in case you ever considered to revert that decision I think we could actually make it work.  But for the current PR you're working on we don't need that, you're right.
