While I agree that baking to multiple textures is useful, it is a different
use case altogether. A per object "bake image" approach may be good here.

Also, might I suggest a per object (or mesh) uv/image pair instead of doing

This is what the second proposal is about more or less, enumeration on a
per material, per texture slot basis. I can't think of another approach
when multiple textures may be used to influence the same shading attribute
(specular, diffuse, etc.)

Having a per object uv/image pair is not good in my opinion: The
obfuscation in the current approach is derived from two factors:

1) The user expects painting to have an immediate effect on rendering
2) The tediousness of the setup process

Having a per object image will help with 2 somewhat but the confusion with
1 will be the same.
