The people that were using retirement extension at the time when it was increased were grandfathered (they didn't have to meet the new requirements). If(big if) it were to be increased would probably only apply to new retirees not the ones already here. But my crystal ball is no better than yours and speculating on what might happen someday is something I don't spend a lot of time on. Guy on YouTube said world end next month so better spend that money now.
