AFAIK, the info like this is not supposed to get back to 3rd party
client in a clear form. JWT and SAML (OAuth2) tokens address it with the
use of claims - I think they only start making sense when we have
identity providers involved. In a simple 'bearer' case this info is
supposed to be retrieved on the server, or in advanced cases, one can
imagine encrypting this info.
Besides, an info like you typed above would not be of interest to Java
servers only hence I was implying that was an impl detail.

One can certainly come with the above format too -- if that proves to be
of interest

They have few flows with no user involved. As for the mainstream flow,
the browser is assumed but I guess is not strictly required, as far as
the interaction with the user and support for the redirections are concerned
