Also keep in mind that a protocol allows the method declarations to
stay in one place (the protocol definition) without requiring them

Consider your idea that you might as well just put the declarations
in the object. You could do that, but then if the protocol changes
in any way, you run the risk of having objects that are no longer
conforming but do not trigger any errors on build.
Right, but (a) you don't need formal protocols for this (an informal
one can be used just as well), (b) beware that it might not work
quite well with separate bundles.
