First, there should be a "regulatory notice" coming which can be as early as next week.
Then, some brokers worry that they may lose customers if customers jump to others brokers that implement the new rule immediately after the "regulatory notice", so there is a limit on the earliest broker use of the new rule: 45 days after the "regulatory notice".

“With approval on an "accelerated basis", we would expect regulatory notice as early as next week. At such time, the 45-day countdown would begin.”
