Re: [csswg-drafts] Proposal: a way to _not_ reverse an animation's timing function when it plays in `reverse` or `alternate` direction (#12978)

+1 to this request.

Instead of tacking it onto `animation-easing`, why not an extra keyword on the `animation-direction`? The concept of not reversing the timing functions does seem very much linked to the `animation-direction`. And it also wouldn’t require implementers to implement the `animation-easing` functionality first.

Something like `animation-direction: alternate keyword-that-asks-to-not-flip-the-timing-functions`.

Or maybe a new keyword  for `animation-direction` like `mirror` (and `mirror-reverse`).
