LinuxCNC S-Curve Accelerations

We make machines, on our factory floor, we always have 3-4 machines on the floor I can test, some complete some partially because in construction. our customers have multiple shops running LinuxCNC, but it is in the background, and they don't really know, they only look at CAM, CNC for them is mostly open gcode start, regulate feed, stop if have problem.
The biggest changes we made you have them now in master, not sure how my implementation can help, and it is not in the scope of the OP.
