Impact I can convince the UI to let me do things with an invalid Application. 1. Admin gives me p, michael, applications, *, demo/*, allow, where demo can just deploy to the demo namespace 2. Admin gives me AppProject dev which reconciles from ns dev-apps 3. Admin gives me p, michael, applications, sync, dev/*, allow, i.e. no updating via the UI allowed, gitops-only 4. I create an Application called pwn in dev-apps with project dev and sync the app with sources from git 5. I change the Application’s project to demo via kubectl or gitops (whichever mechanism my admins have given me, because it should be safe) 6.
