Yes, I think this would be good. So far we have identified animation 
groups as something that can be left to a later version. A number of 
other features that are primarily needed for SVG support (like 
MotionPathEffects) could be exposed as opaque objects and we could add 
the methods for inspecting / modifying them in a subsequent level.

Yes, I think what would help here, though, is tool support. If we had a 
version of Bikeshed, for example, that supported #ifdef-like 
functionality, that would help. Otherwise the maintenance required to 
keep the submodules and the "has everything" version in sync is a bit 
tiresome.

> It seems that Element.animate[1] in a reduced form (without AnimationPlayer) is one part of this subset. I am not sure how much of the introduced animation model is really needed to harmonize CSS and SVG Animations initially. I hope we can reduce this as well and incrementally add things back.

I think if we had the tool support we can start hacking away. I think 
we'll want AnimationPlayer in the initial subset, however.
