That is all well and appreciated but the issue is only that TOS4.x is repeatedly cited/advertised as being the cure whilst it is still in the alpha stage and there are only vague hints that it may arrive production ready till end of this year, implying uncertainty that this will be achieved.
Almost 1 year ago it was stated that TOS4.x would be eventually in beta by end of 2018.
Certainly the dev team is doing as best as they can but that developers have departed and not being replaced, plus at the same time adding the MOX workload, in all likelihood has not aided the pace of development and the consequence is that users ultimately paying the price as being a in limbo between out of date core components with the LEDE repo and some alpha state that is still facing all king of issues on its own in the TOS4.x trunk.
