Interesting but my spider senses are telling me that apart less gcode, as you said and touched with your hands, there will be no printing quality improvement.
...you still have a X and Y stepper not a new nozzle rotation stepper which is triggered by G2 G3.
stuttering? Go for dual Z or something mechanical. For mechanical sickness the best cure is always a mechanical therapy, not a SOFTware one.
Anyway related to that I deactivated
G2/G3 Arc Support, it save memory on my tight ass melzi board and AFAIK no slicers SW support arc anyway.
Another intersting fact I read is that slicers eat only lines and points not arcs, so computing properly arc G-Code is a big PITA for the slicer software. I think on Firmware/Octoprint level is the same music.
