The proposal is here:

They explicitly represent each kind of content; rather than having MapLayer
which could do everything (resulting in amazing hacks like wrapping up
GridCoverage as a Feature and then a FeatureCollection and then a
FeatureSource).

Yes.

The last steps in the proposal are:
Update internals of GTRenderer implementations to take advantage of new classes
Waiting on screen map patch
Change GTRender interface to expect MapContent (and MapViewport?)
Update implementation to use layers() list; it is a CopyOnWriteArray so it is
safe
Delegate to DirectLayer implementation
Update gt-swing code to take advantage of new classes
> Breaking new core API (and deprecating old one) is proposal material too,
> it also requires a description of how to go from the former to the latter.
>
> Long story short, I have no preconception against the new classes,
> but would like more time to look into it (whether you want to start with
> a proposal right now or wait for a more informed opinion from my part,
> that is up to you)
Is the existing proposal sufficient?
