Enable Optimistic Concurrency (afterwards)

In the "Data" section, there is an option to enable optimistic concurrency. Is it possible to activate this feature later on for an existing app?

So if you created an app, infered a schema from the DB without optimistic concurrency, then create some custom pages with basic CRUD operations. Finally, go back to "Database" and infer the schema again, but this time, enable optimistic concurrency.

Will this then work out of the box for existing pages or do those need some rework to be done?

There is additional UI for Edit page that will enable record reload in case of concurrency error.
