ok so this is a new proposal. Could you edit https://design.xwiki.org/xwiki/bin/view/Proposal/PageHierarchyLayout and add your proposal there using the same format? I’m asking because we need all proposals to be listed there (and I find it helps to see an example as defined there). Then we can list pros and cons (one cons for this one for example is having 2 places for app code).
