Yes, absolutely!

I think we should nuke enterForEmergencyRecovery and those parts in 
Project that deal with isolated changes. This is one of the projects 
that never got to a conclusion and there is no point in keeping all 
these hooks for stuff that is unused. If you want to keep the interface, 
just raise an error if you ever see a revert == true or so.
