Feature or enhancement

Proposal:

Python 3.10 retains only the PEG parser and removes the old parser (you cannot switch back to the old parser using "-X oldparser" to save memory overhead). So, is there a way to reduce the memory usage of scripts with the new PEG parser? Some machines are sensitive to memory usage.

Has this already been discussed elsewhere?
