Not including geocaches into OSM

Many mappers recommend to keep geocaches out of the database due to several reasons. Here are some from the latest German discussion.

    Importing geocaches from other sources is almost impossible due to license issues.
    The Opencaching Network already serves geocaching information under a CC-BY-NC-ND license.
    Geocaching has its own databases. Duplicating information creates a maintenance issue, e.g. when caches are temporarliy disabled or archived.
    Geocaches do not connect to other OSM objects, are hard to verify and do not support to guide the way.
    There is no public interest to render this data except for geocachers.
    Some caches are only for an event or a short time period.
    The most types of geocaches require a geocaching community or more detailed information which cannot be served by the OSM.

For the last reason there is almost no type of geocache which can be included into the OSM except traditional caches for example. Hence OSM is not a good place to provide information about caches itself.
