I updated ics29-fee-middleware to the latest changes of main, so I think rebasing off of ics29-fee-middleware should get rid of the diffs that were introduced into main by other prs. For future reference I'd branch off of ics29-fee-middleware when making a pr into that branch so commits to main aren't included in the pr review

It might be easier to fix the diffs by creating a new branch off ics29-fee-middleware and then using git cherry-pick to move your commit over to the new branch
