Solvespace has a fairly robust solution to this problem - for the cases that it handles. It does not create accessible edges for things like the intersection of surfaces, which won't be a big deal until we have a chamfer/fillet tool where you might want to modify those edges. But change an underlying sketch all you want and all geometry built from it will remain intact except for stuff built on something you delete.

IIRC the FreeCAD solution tends to create names of ever-increasing length as you continue building.
