Is the https://nuxt.com/docs/4.x/examples/features/layouts doc ahead of its time? Because it lists a cool feature about defining layouts via routeRules, but it appears the MR for this feature has only been merged 3 weeks ago and no nuxt release has happened since then? I have updated nuxt to the latest and it does not work as the docs describe. I also get a TS error that appLayout is not a valid property for routeRules, further hinting that this does not exist yet in the latest release?
