Transform shortcuts in animation keyframes

[jaydenseric]

Is this suported, and if not, could we add support for this?

@keyframes test {
  0% {
    scale: 0;
  }
  50% {
    rotate: 90deg;
  }
  100% {
    scale: 2;
  }
}

Should compile to:

@keyframes test {
  0% {
    transform: scale(0);
  }
  50% {
    transform:  scale(1) rotate(90deg);
  }
  100% {
    transform:  scale(2);
  }
}

I don't expect this to work when combining animations, just within one keyframes declaration.

Manually doing the calculations when combining several transform operations in one animation is really hard and annoying. This is the primary use case for the new transform properties and to be able to use them in this way now would be beyond awesome.

It would be too much effort at this time to calculate the offsets between keyframes.
