Comment 14 for bug 1552792

The aptcc PackageKit backend developer told me that autoremove is already supported for more than 5 years, since this commit from 2012: https://github.com/hughsie/PackageKit/commit/94a5e71ded685720e49f17dc6ee21716b33ac177

But it still does not work when using pkcon or GNOME Software. Maybe it is not enabled by default?
