First, the reason that some features can't be uninstalled by themselves
is because other features require (depend on) them. In your screenshot
example, you'd have to un-install everything that depends on EMF in
order to uninstall EMF itself.
As fro rolling back, I think you want to look at the Installation
History tab where you can select a previous state and revert to it. This
eliminates all the guesswork inherent in trying to remove an individual
feature.
Hope this helps,
Eric
