+So, in terms of space used for this, if you had to install all 6, would 
+this tax the system so much and risk filling up the hardrive needlessly.
+
+If not, would this cause your installation to misbehave.
+
+It not, if a rollback were done, could all 6 as well as the new F be 
+removed and the old version restored?
+
+If this is possible, would this have an impact on devs preparing 
+Backport versions with rollbacks?
