Separate keyframes for mask feather

The feather mask tool was introduced, like 10 years ago.

And still I have yet to see a single artist using it.

The reason is simple, and it had been brought up from the very beginning: the feather keyframes are the same as the mask shape keyframes - it's ridiculous.

Every roto artist in every software does shapes first and feathering later - but this workflow is impossible with AE - if we do shapes first, then we have to redo the feather on every single frame with a mask shape keyframe on it.

Can we pleaaase have a separate feather keyframe track?

Most rotojobs require like 20-30 mask shape keyframes but only 2-3 fether keyframes - there is no reason why these two properties shouldn't have two separate animation tracks 😕😕
