I guess we will have to wait and see. For a "wanted feature list" it might be better to post in the official gc forum, although I don't think a list will make a difference.
Regarding info, stats etc. Right now they have "retired" old Labcaches with Adventure Labs.
Those are at least supposed to be integrated at the website/map. But for interpretation of stats etc there might be a problem: If the "new" Adventure Labs get more meta data (even retrospectively), the old Labs will not, but they are the same "cache type" stat-wise. So it could be that for say statistics evaluation some will be useable but many will not.
Personally, I would have just retired the old Lab concept and created a new cache type AL, so they don't interfere.
