The real issue is that any plugin in the WP Plugin Repo that is tagged “buddypress” is automatically listed in BP.org’s Extend Section. So, any plugin dev that uses that tag will have their work listed.
We could request that plugin devs use the tag “buddypress-compatible”, instead of “buddypress”, when tagging plugins that are not dependent on BP but can run under BP. This way, only those plugins that are truly BuddyPress specific (dependent) will be listed in the BP.org Extend Section. Of course, it would be up to each plugin dev to honor that request.
