This is what you stated in red below:
"Finally, it does not address the other problem, of the diodes in the alternator being destroyed on a disconnecting BMS."
It's a myth, only applies to a case where the primary battery is disconnected from a running alternator that is fully fielded (low battery SOC). That would be what is referred to as a battery dump. Some call it load dump but really, it's a battery dump.
Read my post again. If the chassis or vehicle starting battery is between the alternator and the LFP battery, the vehicle battery would absorb any transient spike if a BMS would disconnect.
To be honest I did not read all posts. I then assume that this thread is actually about discussing a setup where there is always an additional battery, presumably Pb, parallel to another battery protected by a BMS. In that case I agree with you.
