It's basically the feature level of the specification.
Here's level 1: https://www.w3.org/TR/css-transitions-1/ (this is implemented in JavaFX)
Here's level 2: https://www.w3.org/TR/css-transitions-2/
There seems to be an ongoing discussion around different color interpolation options, but nothing has made it into the level 2 specification yet.
