Definitely!
But I found it easy to write my own -
async def anext(aiter):
return await aiter.__anext__()

I am not familiar with your terminology here, so my comment may be way
off-track.
I use 'bulk iteration' a lot in my app. It is a client/server multi-user
business/accounting app.
If a user wants to view the contents of a large table, or I want to print
statements for a lot of customers, I can request the data and process it as
it arrives, without blocking the other users.
I find that very powerful.
