When browsing the diff history, I believe &diffonly=0 and &diffonly=nonzero, which currently override the diff suppression preference, should cascade to the "← Previous edit" and "Next edit →" links shown in the diff table. This would allow, for example, quick diff browsing with &diffonly=true for users who did not want to load a large page or change their preferences to do so.
A less easy bonus task would be to apply this cascade to all pages that register diffs. Recent changes and action=history for example. I am thinking similar to how &bot=1 cascades to all rollback links.
