That is a very BAD idea. PCB is not a drawing tool; it understands things
like design rules, connectivity etc. It makes no sense to have software to
trace connectivity on the silk, mask, keepout, etc layers or to not be able
to understand that metal layer DRCs are different from the silk layer, or to
deal with elements having various "grouped" metal, mask, and silk features
if all layers were arbitrary.
