i would suggest not to make same mistake as Nokia and place all community packages as one meta package that would update all the packages at once and enable the opportunity to install and uninstall certain application without breaking this meta package. what i mean is if i decide to replace mediaplayer with qtmediaplayer the update of community-ssu fremantle wouldn't reinstall mediaplaye even if it's included as it was with official Nokia one when all fixes and packages came in one update. for example everytime i updated if i'm not mistaken i got amazon app and facebook installer installed on system. as well it would not only improve the roadmap of updating all packages/projects separetly but independently (not freezing realese for testing), but also help to build your own system with your own apps of choise.

if this is already a plan or works out of community box, sorry for misunderstanding.
