Feature Request: Cubic subdivision for large SUPPORT structures (subdivision in Z-direction)

[DrWoo 2]

I just read about the Cubic subdivision infill feature introduced in Cura 2.4 and instantly thought about having had the same idea some time ago for support structures with a larger footprint:

Think of starting with few rectangles at the print bed and then subdivide every X layers as closer it gets to where the support is needed. It involves some sagged or even failed bridging on the first layers of each subdivision, but those bridges will heal themselves using the consecutive layers on top.

This enhancement (I tend to call it Cascaded Supports) would save quite some time and filament on voluminous objects requiring supports.

To give you a better idea, here’s a conceptual illustration, an X-ray bird's-eye view and a view from underneath (bed’s perspective).
