Given these criteria, the most promising ideas so far appear to be notifications about contributions (or contributors) to a page you edited. We might also consider 'mark as useful' or 'feedback' notifications for projects that seem likely to adopt these new features, but those would have to be viewed as lower priority than the contribution notifications. Other ideas may have to wait until future releases, sadly.
Generating Echo events for every edit on Wikipedia for every editor of every article (even if they are bundled or filtered to a certain group of users) would quickly explode the database. It would also likely crash the servers with massive numbers of expensive queries – for every edit, we would have to look at all previous edits, and determine if those editors (which could number in the thousands) should receive a notification. Considering that we average more than 3 edits per second and have limited processing power (saving edits already takes 30 seconds or longer on long articles), I'm not sure this would be feasible. It also overlaps with existing watchlist functionality. Of all the ideas proposed, I think the contribution notifications are the least feasible and the least useful. The 'mark edit as helpful' idea seems like the best one to me so far, but would probably make more sense for E3 to develop than E2 (so that they could experiment with different UX and A/B test them).
