Use case is to give user ability to change display of content in frontend. For example, there is collection like blog articles (image, title, text), and there is field, responsible for displaying it as grid, or as list. And I would like to bring this setting (editing of that field) to frontend, so that user can see changes instantly.
Yes, you could do that. Although you would need some sort of JS solution to update the DOM while also updating the field value. Maybe use a select field where user can change the value, submit via JS, then make an Ajax call to the API or a custom route.

Thank you, discussed this question with friend, probably better to leave all in backend.
