If you are using role-based forms because you want to restrict the information people might view or edit, consider creating a form that has a minimum of information displayed.
For updated entities, these forms appear within the main form to display additional data for a record that is referenced by a lookup field in the form.
Yet there are still a number of entities that retain the appearance and capabilities carried over from the previous version.
Entities using classic forms weren’t updated because they are not used frequently by most people and updating them wouldn’t have a significant impact on the experience of most people using the application.

The form order determines which of the available forms will be shown by default.
