If I understand correctly the question, then that is "mission impossible 5" to implement jerk limitation in the feedback loop, closed by servo drive, because AFAIK almost all of them are running closed source firmware. Jerk limitation is available only in feedback loop, closed by LinuxCNC, and I think that it is sufficient - imagine the torque loop closed in servo drive and velocity loop closed in LinuxCNC - requested velocity from LinuxCNC will be jerk-limited, thus will have s-shape curve instead of trapezodial. It does not matter if servo drive has jerk limit or no, it is already there in requested velocity.
