I have been adding various endpoints into the Wikia as I come across them while watching my browser activity. Most notably, for endpoints which seem to have versions (denoted by the V{n} on the end), from what I can see still return mostly the same output so I've set up older versions as redirect pages (turns out when you rename a page - not only will it throttle you after about 4 page renames - but it actually creates a new page and puts #redirect [[NewPageName]] in the body of the old page, which you can still edit by including ?redirect=no on the url). I've then included an "Old Endpoints" section after the Summary, which lists the previous version endpoints. That being said, I have seen Bungie.net reference new and old versions of the same endpoint, but I'm going to assume the newer versions are meant to replace old ones (eventually).
