I admit I never animated a gradient so far. But I would expect in cases
where the number of stops doesn't match, simply doing a fade between the
2 gradients would be the best bet.

I wonder if stops having more or less "influence" on the gradient would
make sense.

Otherwise I would expect being able to animate every channel of every
stop separately. Plus timed adding/deleting stops (expressed as lifspan
of a stop).
