The people I've seen post about it also pointed out the stress-free planning they can now do.
So for AK, they maybe already have FoP, Navii and Safari booked, with ROL reserved viewing. At 60 days they only need to pick up EE, Kali and Dinosaur - no problems there.
For Epcot, they have TT, FEA and Soarin sorted, with Illuminations. No issue getting SE and whatever at 60 days. No rope drop required, no PPO to race to Soarin, etc.
One guy reckoned he'd pretty much paid for it by cancelling EMM, desert party, PPO breakfasts. And he had already booked CL before news of this came out.
The other side of the coin though - no overlaps, so you'll be "committed" to 4-5 hrs to get through all FPs, plus a nighttime show. Which minimises the time spent at the resort, taking advantage of the CL for which they've paid an extra $$$$ for!
But all the same, if this was extended until SW:GE opens, just think of all that stress removed before the 60 day mark.
