only if you *actually* install all possible combinations, which seems 
unlikely.  If you're worried about all the old cruft hanging around 
taking up space, maybe looking at Nix's garbage collection and other 
features would be good sharing of experience.  Maybe (with the user's 
permission) pre-emptively upgrading some things sometimes would help... 
not sure.
