Adding finalization to objects created for everyasync for loop is likely to have an adverse effect on performance.
Have you benchmarked this?

Runninghttps://github.com/python/pyperformance/blob/main/pyperformance/data-files/benchmarks/bm_async_generators/run_benchmark.py showsBenchmark hidden because not significant (1): async_generators. My benchmarking setup isn't very accurate though.

I plan to land this later today if there are no further concerns.
