We added a new `ThreadedTimeBasedAnimationsAtHighFrameRateEnabled` flag in 307177@main to only update monotonic threaded animations at 60Hz on iOS while we work on selectively opting in only "high impact" animations to run at a higher frame rate. We introduced the notion of "high impact" animations in 307339@main and only run high frame rate updates for those on iOS (provided that flag is enabled). This meant only transform-related animations can opt into a high frame rate. We need to be more selective still and only opt into transform animations that actually are high impact, for instance those that will travel on screen at a velocity that would be visually be improved with updates above 60Hz.
