That's more or less how I did understand it. What I recommend is a
description for the user, which does not use eieio terminology. It could
be a barrier for people not familiar with eieio.

Maybe there is a misunderstanding. If dbus-introspection.el would be a
part of core Emacs, I recommend to move existing dbus-introspection-*
functions *from* dbus.el *to* dbus-introspection.el.
If dbus-introspection.el will be offered via ELPA, this is not useful.

I would say yes.

Maybe. Or they are kept in dbus-introspection.el, and are called
dbus-introspection-*.
