So you propose to just let Ops personnel handle attaching volumes and renewing certificates, that these arent technical problems but just one of team structure?
Please, do describe your solution for the concerns above. So far Ive only seen equivalents of Greenspun's tenth rule
But k8s was invented so that "dev" and "ops" teams could play nicely when they are different org structures, with their own budgets, deadlines, etc.
If it solves some technical issue then that's incidental.
