[issue30782] Allow limiting the number of concurrent tasks in asyncio.as_completed

I would like to see this implemented. I run into memory and speed issues when running with 1000+ tasks quite frequently, and have to write my own rate limiters around it.

It doesn't look to me that it is adding a large amount of complexity to as_completed. This was closed in 2017, perhaps it is worth revisiting?
