You shouldn't rely on that, some may start applying the restrictions in their own blocks at 0% and others only at 90%. Until it becomes a consensus rule it is just part of the standard policy (and we shouldn't rely on nodes following the standard policy).

It would be a consensus rule. If >75% of the blocks in the last 2016 window have the bit set, then reject all blocks that have the bit set and fail to meet the rule.
