Comps as materials for 3d models (AE Beta)

In Element 3d by Video Copilot, there is the option to use comps as materials for 3d models.

It would be extremely useful if it were to be possible to set comps/precomps in the same active comp as a 3d model to be the material for that model or a texture for one of the materials in the 3d model.
Do you (viewers of this post) think it would be useful/cool?
