If the devs remove the ability to do Tor via Tor and don't add layered entry guards themselves they will essentially be flipping off anyone who wants an actually highly anonymous hidden service. In the mean time, Tor via Tor still works and SR should be on the schedule of cutting edge anonymity not waiting for the Tor devs to play catch up. They are balancing the overall health of the network with the anonymity of hidden services, and right now they are not favoring hidden service anonymity as much as they could be (or should be imho). If they remove the ability to do Tor via Tor and don't replace it with layered entry guards for hidden services it will really piss me off and it is not in the best interests of hidden service anonymity.
