In some cases, I'd like to give in conditional editability (based on attribute or expression) for a whole data view just like the individual widgets within that data view. This would prevent me having to change the conditional editability for every widget seperately or (in some cases) prevents making duplicate elements on a page, thus speeding up the workflow.
I'm aware that, in many cases, this can also be resolved within the domain model security. But still there may be some cases in which this can be valuable.
