The FAA (and all government agencies) have a proceedure they follow. (1) A problem is pointed out.
(2) The FAA works out a solution.
(3) A "Notice of Proposed Rulemaking" is issued in the Federal Register. That opens a (normally) 60 day comment window.
(4) At the end of the 60 days, for big issues, there may be a meeting of concerned parties.
(5) After the comment are looked over and the meetings are done, there may be a "Revised Notice of Rulemaking" with another comment window.
(6) Then after a group hug the Final Rule is published in the Federal Register. This will have the effective date, say 30 days after the publication date.

We're at step 1 right now. One of the last NPRMs I saw was whether to change Part 25 to allow yellow alerting lights in the cockpit along with amber. Don't hold your breath for any quick change.
