> I just discovered that we're still using a boolean flag {{timelineServiceV2}} after we introduced {{timelineServiceVersion}}. This sounds a little bit error-pruning. After the discussion I think we should only use and trust {{timelineServiceVersion}}. {{timelineServiceV2}} is set upon client creation. Instead of creating a v2 client and set this flag, maybe we'd like to do some sanity check and make sure the creation call is consistent with the configuration?
