if I just keep one zedtoken with the latest update, and pass it on every request, is there any benefit at all to using the zedtoken vs doing doing all requests as fully_consistent? its hard for us to find a "parent" to assign the zedtoken with some granularity, because we have a hierarchy tree, and they are all children of the same top node another option we thought about was keeping the zedtokens per-user, but that may lead to some problems. Maybe we should simply use fully_consistent for now, since we arent really expecting a lot of load And another option, to use the direct children of the top node, since the top node is for superadmins anyways
