Agreed.

I'd like to suggest a further change in this, so that in the
y-direction the image is neither fitted or repeated, unless repeat-y
is given. The same change applies to fit-y (and repeat-[xy])

This means that the value definition would have to be altered to
accept two values. Then repeat, fit and no-repeat would be shorthand
values for repeat-x repeat-y, fit-x fit-y and no-repeat-x no-repeat-y
respectively.

The benefit of this is
a) that the author gets greater freedom
b) that the implementator have independent values for the x and y
   axes, which I think simplifies the implementation (yes, I am
   writing a CSS implementation, so I think I can have opinions of
   what implementators (or at least one implementator) thinks).
