There is a big difference between PAUSE and emergency STOP. If everything goes to hell in a handbasket I usually retreat to the safety of the mains socket and kill the power there. This does preclude braking the spindle at the VFD but it is comforting to know everything will soon come to a halt without removing any more fingers.
Pause OTOH implies a restart so it is purely a software driven thing which involves looking in to the G code future and creating a plan to get everything back up to speed. A well written pause is a joy to behold and well worth playing with
