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?
