AquaHot Manual clicky
Depends upon the model of Aqua Hot on whether they place that warning in the Owner's Manual or not it appears.
From my Aqua Hot Manual, "WARNING! YOU CANNOT BLOW DOMESTIC WATER
COIL OUT WITH AIR TO WINTERIZE AQUA-HOT."
Doesn't make sense if using compressed air "correctly" ........
I suspect it’s another instance like the need to ‘exercise’ a generator, even though nothing but the ownership of Onan changed, suddenly there was a need to run them on a monthly basis or all sorts of terrible things would happen.

Yes there are, anyone with a aqua hot and I assume other similar systems require antifreeze added to the water lines. They can't just be blown out with air. Any water left in the system could burst the copper coils. States right in the manual.
I’m at a complete loss to understand why the coils in the AquaHot system would be any different than the rest of the water system
Can you explain why you think they are?
It's not up to me to decide. I know my systems and have read the manual. Like you said you know what your manufactures procedure is, so do I.
Here's the exact print from my owners manual
Winterize the Aqua-Hot
The Aqua-Hot can remain on during the winter months. If the motorhome is to be winterized and stored over the winter with the Aqua-Hot turned off, the Aqua- Hot domestic water loop must be winterized with FDA approved RV antifreeze to prevent freeze
FDA approved RV antifreeze must be pumped through the Aqua- Hot until the solution appears at the hot water side of a faucet. The on-board water pump can be used (see illustration) to purge water from the Aqua-Hot domestic water loop.
Refer to the Aqua-Hot owner’s manual for complete winterizing instructions. If the system is operating from AC electric and a power outage occurs, extensive damage to the Aqua-Hot may occur.
From aqua hot manual
Not winterizing the Aqua-Hot when freezing temperatures are present will result in serious damage to the Aqua-Hot’s Domestic Water Heating System. Also, be sure to use an FDA approved, “GRAS” rated antifreeze for An FDA approved “GRAS” rated winterization antifreeze must be used.
YOU CANNOT BLOW DOMESTIC WATER COIL OUT WITH AIR TO WINTERIZE AQUA-HOT.
I hope that helps you. I have ny thoughts why, but I'm not the expert. As I simply stated before, know your own rig and what's required.

Anyone here telling you to just use air and not to worry about it could very easily get you into a whole BUNCH of trouble. It could cost you many thousands of dollars to fix.
In my case the ‘anyone’ telling me to use air is Winnebago (Itasca) the nice folks that built, and warrrantied, my (and many, many thousands of others) motorhomes.
Maybe they just don’t know as much as some others do..........

Can blowing it out be enough? Yes it could, depending where you live and "if " you do it right, and have no systems needing more protection.
Some of the excuses not to use antifreeze are pretty funny. Even using antifreeze you can still have broken pipes if not done right.
