I'm not sure there are any 3rd party text input controls that don't extend from TextInputControl. If a 3rd party text input control does extend from TextInputControl / TextInputControlSkin, will it work?
If we use an internal interface, will this fact "leak" through the public API? That is, if I enumerated the hierarchy of a public API member, will I see this non-public interface somewhere on it? Or is the only way to get a hold of some internal object and cast it?
I'm wondering if we can punt on the problem until somebody encounters it, and in the meantime just use a private interface.
