Feature request: changing the slicing algorithm to reduce warping (of ABS parts) in FDM printers

hi, this is a feature request.

Could prusa consider some change in the slicing algorithms to reduce warping of long (ABS) parts in FDM printing?

In my google searches around for solutions to reduce warping for long (ABS) parts. I stumbled into the following papers:

Warpage of FDM parts: Experimental tests and analytic model

in the above paper / link, it shows that the continuous length of parts is a key factor that is observed in warping, lifting of the prints. I think the paper is well researched and coincides with what I casually observed as well, longer parts warp more severely and requires a lot of counter measures, use a heated bed, turning off part cooling fan, use an enclosure, etc, but it didn't fully resolve the issue. A heated bed probably helps with the 1st few layers, but cracks form at layers beyond the 1st few layers.

Next I stumbled into this paper

Bricking: a new slicing method to reduce warping

It turns out hexagonal shapes bricks help to reduce warping ! and the idea is to breakout long stretches into bricks so that the continuous length is shorter in each direction and hence reduce warping. The bricks can probably be interleaved so that the edges don't all fall along the same edge, e.g. as like brick laying in masonry buildings.

Could this be looked into and perhaps start with experimental features so that Prusa slicer users can try them out?

This can perhaps be an optional selection as like infill etc, just that this is different from infill in a sense that it affects the boundaries as well.

This has potential to help solve warping in large flat layer prints such as printing box enclosures, which often has large lengths by virtue of the function needs.

 Thanks for reading,
