need you forget what happens after the grace period.
miners are then satisfied that atleast OVER 95% of nodes have the rules ready... then the miners do their own flagging and consensus mechanism over another block measure.
Miners don't care about the situation with the node count and they should not be interested it. The number of nodes in a small period of time is a horrible metric as it can be easily manipulated.
seriously wake up to reality and join the conversation, get out of the fantasy doomsday nightmare that is not reality and start thinking rationally about how things will work in the real world.
Ad hominem & no argument once again.
miners wont jump first, they will wait for users.
Again, the "users" that run nodes are a small minority. There's no way to properly "wait for users" as there's no way to "measure these users".
