Can you pass a form to another form?
No. You can implement just one or, say, two. Nothing prevents you from putting everything you need in an interface, which would mean, for example, “access to a form from other forms”. It still has the benefit of passing only the interface to precisely limited functionality.
What does it mean to pass interface to another form?
Passing the interface is not a “change”. Before doing anything related to form sharing, pass a reference to the form instance to another form instance. With interface, you pass the instance of the same form but in the form of an interface.
