Has the jury come to a conclusion?

, but I put a lot of stock in your findings...
It sounds pretty logical to me.
Water is a very good conductor of heat, but it's also chemically active.
Especially where dissimilar metals are involved.
If you make the coolant chemically inert, then corrosion should not occur.
Sort of like placing a bar of pure iron in a container filled with inert gas, such as argon. No oxygen, no rust.
And since the the coolant has a much higher boiling point than water, there's no real need to pressurize the system as high (as needed with water to raise it's boiling point).
The only disadvantage I see is the initial purchase of the coolant, and the required draining and flushing of the entire system.
However, once that is all said and done, the coolant is there for the life of the engine.
Pretty radical stuff to me, despite being around for 30+ years, it appears.

Especially the ThumperTalk link (for bikes).
