Why doesn't the GH "Pull curve" accept meshes and Sub-Ds?

OK, this doesn’t seem to raise much interest.
Anyways, I used a kind of “Geodesic on mesh” tool from the “Meshpath” plugin, and it kind of did what I needed.
Funny that’s not a standard tool, as creating geodesics is the basis of a lots of good stuff…
I know it can be done with Kangaroo, but yeah.
