Sure, but that's only in the PolicyKit authentication dialogs and that's
intended [1]. However your session-daemon that _provides_ this service
would show the consent prompt, e.g. "The application Totem wants to
install XYZ", long before the PolicyKit authentication dialog would ever
appear.

You didn't reply to my other questions. Slightly annoying ;-)

[1] : Keep in mind that authentication prompts are almost always an
evil. On a properly configured the user should have the authorizations
that he needs. So for example if the package to install is signed by a
trusted party there wouldn't even be an authentication dialog as we'd
grant .install-trusted-package to the user (either explicitly or he
gains the it implicitly via authentication and retains it).
