Not a mod, but as a rule of thumb runs from before rules were changed are allowed to stay up because they were verified under the rules at the time the run was submitted. Runs dont usually get retroactively removed. The reason why 60fps is the floor is because lower fps give higher speeds from wallkicks, so if there was no floor the run would eventually turn into playing a slideshow just to get the highest possible speed.

Out of bounds have been allowed in any% for years and a normal part of speedrunning, CKF exists to level the playing field for all runners so certain hardware is not a requirement to run, and i shouldnt really need to explain why being able to see your speed in a speedrun is allowed.
