There might be a need to have some objects that only work with a single data type, which would raise some questions. If I wrote an object that only made sense for colors or texcoords then how would those be distinguished?

i cannot think of such an object right now (as long as it is about mathematical transformation of the arrays) : even if some functions do not "make sense" there is no reason to prohibit them. on the other hand, sometimes you might want to generate e.g. normals out of the vertex-positions, and probably you would need the same for color *very* seldom; so i would imagine an object [vertex_normalsgenerator] (or whatever name) that only applies to the normals.
