I don't know but the Bitcoin developer or the ordinal developer should figure this out or the fee will be this high for a long time.
There is no "Ordinals developer". There's only a bunch of people throwing programming shit at the wall to see what sticks.
As for bitcoin developers, well the default tendency is to do nothing, except for a small minority of them.
There's no easy way to undo ordinals at this point. You are going to need to gather enough capital and mining power involved to basically push for what would be a BTC hardfork without ordinals, and this would need to be done in a way that guarantees no future ordinals are possible, but then again, how do you this without causing another hardfork civil war, and how do you do it without getting rid of taproot? because if taproot is possible, I believe there could be ways around any restrictions put into ordinals to come up with alternatives.
