In the specific case of data transformations, this is already the case.
The backends are sent the raw data + a transformation. This allows file
formats to write out untransformed data and have the renderer of that
format do the transformation. Unfortunately, all of the backends end up
doing the transformation in software anyway, since all of them scale the
line width along with the path data, which is never what you want for
plotting. (The exception to this is the SVG spec, which now contains a
flag for this, but that spec is so new we can't use it because it isn't
widely implemented).
