I have heard that the time for a SO to upgrade to JFO may increase to 5-6 years (keep in mind that it may not be accurate; just something I heard from a currently employed SO). Also, bypass pay due to DEFO being hired and extendees past 55 years old is apparently not being paid like some SO had expected it would be after reading their conditions of service (again, I can't substantiate those claims I heard from a third party; don't know how true it is).
