In Carmack's talk this year he said fovisted rendering was basically a mistake. A lot of it was due to hardware implementation details, but it didn't save much GPU resources for the quality hit you took.

One nice benefit of the Quest 2 is that it can run Quest 2 games without be it.

It's still a feature in the Oculus runtime but they only recommend it in specific situations now, and they try and manage the quality outside of the game because way too many developers just cranked it to Max and it made their games look terrible.
