Old SubSurf Optimal view?

I’d like to know if it’s possible to view a mesh that has SubSurf Optimal enabled on it as it was viewed in 2.34 (and older versions) in Edit Mode. That is, the vertices would stay in the same place and an “edge” would connect it to its translated position on the surface.

I doubt that it’s possible to see it like this in 2.35, but I was hoping there was some sort of toggle that I somehow haven’t found. If not, I think it would be a good re-addition to 2.36 (or maybe someone could make a patch?) because it really helped me to see the overall “curvature” of a mesh so I would know which vertices are causing a part to look bad.

Thanks in advance.
