My opinion is to allow the FPSFix in some form on the leaderboards. I'm not particular as to whether that's through splitting the boards or a hidden filter or anything else. Some distinction should definitely be made if allowed.

However, I'm still learning the run and have no interesting in grinding for a top time. When I did practice without this fix this week, while everything was doable, I definitely noticed the difference. The FPSFix provides enough of a quality of life improvement for playing the game, that I'm in the camp of continuing to use it even if it gets banned from the leaderboards. So my main bias is simply, if/when I get a run I'm happy with, it would be neat to see my name on the boards.
