I agree.

Ideally, there are two types of profiles:

Archivalists who have a lot of storage and need pretty good uptime, but no need for high bandwidth. They should be rewarded for archiving, because they don't really get a lot of upload credit.

Distributors who need low storage, high bandwidth, robust connections when online, but not necessarily high uptime. They just distribute the new and popular stuff.

I think the better private trackers recognize this and have systems in place to provide credit to people who seed rare torrents.
