Correct.

Yes, I ignore autoremove in the yum backend only. I think it's only
really useful on embedded systems where space is at a premium.

We only enable allow_deps TRUE after we've done a GetRequires, and the
user has confirmed the other packages being removed. I don't think any
of the GNOME frontend tools enable autoremove at all.

Sure, that sounds sensible.
