I know it smells, but moving it to refactoring this packages is no go for merging it in 0.44.x

Can we add a TODO for future scope?

TODO doesn't make sense here because this is merged only for 0.44.x, not in master.

Are we certain that auth is the only module of the ordered set that matters? As in no external chain modules will have this same issue?

It seems like this approach will still work with our workaround that sent in each module one at a time out of an array to control the order.

LGTM, just needs changelog entry.

Issues for other chains migrations will still persist, but perhaps thats out of scope for this PR. Documentation for this as an issue should propogate to the upgrade instructions wherever they are.

@ValarDragon right. Also, to be clear this is only a temporal solution. In 0.45 we will have something else.

Issues for other chains migrations will still persist,

Yes, if the chains will have other dependencies, then they will need to use a hack as resented by Osmosis / Dev: https://github.com/cosmos/gaia/blob/0dd70958a10b24703c09c43745611779f0e7970f/app/app.go#L572-L593

No, I will update the documentation and migration guide. Proper change is breaking or requires a hack described above.

This is going to make syncing nodes for already upgraded chains much more complicated if they upgrade

Good point. We didn't thought much about syncing from genesis. We were following the decision / discussion re 0.44.1 release here.
It seams we need to do more major release :)
