It "injects" accounts. The part that does this is mostly in the
downstream packaging. Also you can uncheck the box "allow guest" in
the GUI :)
I don't /think/ it's on by default in our code, but Ubuntu packaging
turns it on.

You can't really do that, next package upgrade would overwrite it.
Either way, it's meddling in a terminal and I don't like that for
something trivial.

No, it uses Polkit in the middle. You still get prompted for a
password, and need the right privs.
You can't edit QML logics in the GUI, that would be a bit weird.
