Can you please explain how having a longer grace period makes it any safer? Once the fork reaches the LOCKED_IN status, the fork will become active after the period is over. How does having a longer grace period make this any safer besides just adding more waiting before it goes active? You said something about rolling back the changes. There is no mechanism for roll backs, and the whole point of the soft fork signalling is such that there is no need to roll back anything because miners have signaled that they are supporting the fork.
