You bring up a good question, but that still dilutes the subject. Those aren't maemo applications, so if another site hosts them, there isn't any overlap or conflict with existing prescribed resources.
EDIT: I see Andrew partially disagrees with me on what constitutes a maemo app. That's fine. I just think that most of what dkwatts listed are support files, not apps-- BUT I do think maemo should broaden to embrace them (not the Flash).
