Cool, I think apt can do that too. YUM might be able to do that with a
plugin, I can't remember.

Sure, as always :-)

We have at the moment:

    <method name="RemovePackage">
      <annotation name="org.freedesktop.DBus.GLib.Async" value=""/>
      <arg type="s" name="tid" direction="in"/>
      <arg type="s" name="package_id" direction="in"/>
      <arg type="b" name="allow_deps" direction="in"/>

Which basically means we can signal the package to remove, plus a
boolean flag to indicate if other dependent packages can also be
removed, so for instance, if removing openoffice-core also removes

I think what we need to do is extend this method with another parameter
"cleanup_deps" which would mean clean up any package that was installed
with this one to satisfy a dep. We don't need another method as existing
backends can ignore the request to no ill effect.

Does that sound sensible?
