@nicolaasmatthijs In those cases we still leave a RestAPI method for the global-admin-only functionality (activities has `collect`, and I think search still has `refresh`.

I think it is tricky to properly reflect the fact that it only exists on the global admin tenant, and just throwing a 404 when it wasn't a global context isn't great. The clearest way to reflect it IMO would be to have a separate RestAPI namespace for admin functionality. Like RestAdminAPI ?
