Well, I'd imagine if you're using procedurals, and would like to make the model more accessable to users of other software packages, then you'll likely want to bake the procedurals to an image that's applied via UV map.

But as far as hand painted textures for an object go, I don't see a reason to be baking anything, unless you wanted to throw in a seperate texture/image of a baked occlusion pass, that can be added at the users discretion or something. Most things that get baked to textures, lighting/spec w/e, other than procedruals, are scene dependant I think, which is up to the end user.

My thoughts on the matter anyway.
