Could you create a separate feature request that goes into more detail about your use case? It sounds interesting, but for clarity we do not have any plans for a permission like that atm, so it would be good to know your full use case in detail to ensure (1) there isn’t (already) a better solution for your problem and (2) whether we need to reprioritize for that need.
Please focus on problem (rather than proposed solution: view permission) for your feature request so we can find the best solution.
