I suspect you don't need this, see if your tests still pass without it. If not
then add a TODO that states which values require us to fall back to legacy.

I still need this when the lists are different lengths. This usually happens
when either 'from' or 'to' does not have a defined value, so the list is empty.
Practically, I could put fill up the different axes with default values.

     default:
         // Fall back to LegacyStyleInterpolation.
