This one point is not completely true. A background image does not  
always repeat, and it is not always 100% opaque. Both GIF and PNG  
allow transparent portions to show the solid color fill (background- 
color) behind them. I would expect a gradient to show through the  
those areas of the image and the areas not covered by the image in  
the same way.

It sounds like you are suggesting to have the 5 methods you mentioned  
by all mutually exclusive. But I would prefer to be able to combine  
solid with background-image, as we can today. Gradients could be  
combined with background-image in the same way.

Disabling the image is only necessary if you no longer want the image  
on top of your solid or blended color, so I have no problem with the  
way that is already done.

In regards to disabling a gradient to show a solid color, this  
becomes a moot point if the gradient is used as a color value. There  
is probably no need to have a gradient with translucency in front of  
a solid color on the same object, or a solid but translucent color in  
front of a gradient on the same object. Which is one reason why the  
idea to use a gradient as a color value for background-color, color,  
border-color, etc. was so brilliant.
