It is the right answer as long as fold{l,r}WithKey are missing in Data.IntMap.

I don't see why being halfway towards a desired state should make us want to go back to the previous state.

{starting point} -> {we are here} -> {here's where we want to be}

it seems it would be more work to first revert to the previous state and then make a proposal to move to the final state (where Map and IntMap are symmetric) than to just move to the final state from where we are today.

But we don't have a proposal for "where we want to be", so if "we are here" is worse than "starting point", we should consider what the prospects of that other proposal materialising are.
