Have you used it successfully such that TPTB allow you to travel to "other places adjacent"? I mean, have you used it successfully to get through customs from any government in power today?

Does the U.S. count? If so then yes I have used it to travel internationally.

At the Matamoros crossing I got to talk a few minutes each time to border crossing guards on the U.S. side. One seemed to think I needed more official documents as "I am guarding an international border". I told him I had crossed six international borders to get to that point [Iowa, Missouri, Kansas, Oklahoma, Texas and Mexico].
