The line in the above quote, "The 12V battery will wear out if this energy transfer is completed daily due to aftermarket loads draining the 12V battery down to 40% or lower," is ambiguous and probably misstated. "The 12V battery will wear out if this energy transfer is completed daily...." seems to imply that if you top off your LVB regularly, it will wear out faster. I would say a correct interpretation is that the line is stating in an incredibly convoluted way, "If you add enough after-market equipment that your battery is going to drain to 40% or 30% every day, you're going to wear out your battery faster." But that will be from depth of discharge and sulfation, etc. I read somewhere else that if you cycle between 50% and 100%, you'll get ~2x as many equivalent full recharges from your AGM battery as you do from doing much deeper discharge/recharge cycles.
If one asks MS Copilot why Ford doesn't maintain the 12V AGM battery at a higher SOC, here's what comes out (no source references given!):

Is there a reason that the Ford Lightning doesn't more actively maintain a high state of charge in its 12V battery?
Sent by Copilot:
The Ford F-150 Lightning’s 12V battery management is designed to balance power needs and battery health. While actively maintaining a high state of charge can prevent sulfation and extend battery life, it also risks overcharging. The vehicle’s charging system likely prioritizes starting power and avoids excessive charging to prevent damage.![]()
