I do agree.If the neck is over annealed the case is scrap anyway.
With many bottleneck rifle calibers, if the neck is properly annealed within a few seconds then removed from the heat source is it likely that residual heat will continue to anneal the neck and that enough heat will be conducted to the case head to anneal it? If as you say the case head is exposed to being heated during the heat treatment then it should be prevented by design features of the machine rather than be compensated for by water quench.
I have used water quench for handgun calibers but don't find it necessary for longer bottleneck cases.
I was more making the point about using quenching to stop annealing. Which as you point out should not be needed on a rifle cartridge that it not overheated. Some folks push the heat limit a bit, and others just try to be extra careful. My annealer is a welding glove and a propane torch, it works so well that building a motorized replacement keeps getting pushed back I favor of other projects. I only anneal rifle cases though, pistol cases just get loaded til they split.
