This will allow for updating the imported geometry without having to rebuild the history tree from scratch every time.
It will be a big efficiency boost for people like me who do the surfacing in Rhino.
It will require that the topology stays the same of course, in order to not get errors in the tree.
I would expect it to handle changes to the surface shapes as long as the main layout stays intact.
Onshape has implemented this very well, Solidworks too has had this for many(20?) years.
