Yes, it is interesting. I've been counting on the Roth conversion ladder to get me through, but the change has had me considering a hybrid solution. Once fully FIREd, I may split up our tax-deferred into a couple of IRAs, and use the 72(t) to give us a baseline income, say to cover all housing expenses or whatever. That way, we can still set up Roth conversions elsewhere to control our MAGI and give us long-term flexibility that 72(t) lacks. The 5+% withdrawals this change allows will make the strategy a lot more viable.
