Some machines (like the shapeoko2) should avoid rapid z motions (G0Z...) because they can miss steps/position when moving so fast on a screw axis. There should be an optional warning that could be enabled for such machines.
NOTE: I encountered this issue using kiri:moto exports from an OnShape model. There were multiple rapid moves in a row. I'm not positive if my GRBL0.8 machine was combining the rapid motions or just losing a bunch of steps in the Z axis (either way ended poorly).
