I think having 'background-rotate' would be a whole lot simpler and easier for authors, and satisfy most of the use cases. The @rule would primarily be for so we can include list item images, border images, cursors, and 'content' images? Doesn't really seem worth it to me, whereas 'background-rotate' would be more widely useful while keeping it simple. The @rule seems like a more complicated replacement of background in order to get marginally broader in what you can apply it to.

Correct - the background-* properties already do a *ton* of stuff.
The problem is when people want similar functionality in all the new
things that accept images.  You list the ones in current CR-level
specs, but even more are appearing, like 'mask' from SVG, or an
advanced form of 'pointer-events' that takes an alpha mask. Webkit's
weirdo independent implementation of -webkit-mask takes the "screw it,
let's just copy them all over" approach, but that's really inelegant
and frankly kinda dumb.
