Loss of 70 largely pointless years of unbroken top flight tagnuttery aside, it depends on where the club is financially by the summer.
The bad side of it is being hamstrung by even stricter PSR rules and just getting deduction after deduction until you become Reading. There's also the complacency factor. Just look at Sunderland circa 2018.
On the flipside, we might absolutely piss it like Fulham a couple of years back and have an utter blast, marking Goodison's last game with a promotion party... Or not even piss it first time, but grow as a unit a la Villa, learn our lessons and become better in the long run.
After today, I think I know which of those scenarios I'd put money on.
