I think you're probably right.

I think Simon was indicating that all compound properties will be
limited via the lack of individual properties.  Of the animatable
properties, I think this only applies to background-position and crop.

As crop looks like it's designed to potentially support
non-rectangular shapes, trying to solve that with individual
properties could prove to be unscalable (e.g. if polygon was
introduced).

A general solution may be to leave individual properties and use a
keyword which means we don't want the value to be affected (e.g.
"same", "passive", "unchanged", "continue", "as-is").

E.g: background-position: 10px unchanged;

This could be a more general approach compatible with the likes of crop.
