It was a conscious decision to have Extras or equivalent out of the pre-installed image in Harmattan. Reverting that decision in normal circumstances would have been extremely difficult but in the current situation I personally see it as basically impossible.

The main reason to keep the community repositories out of the pre-installed / offical image was to have a clear separation with any software coming from those sources in case any legal problem would arise. You have seen the escalation in legal battel in the mobile context. From the many risks around, this one was a risk Nokia didn't want to take.
