There is a school of thought that maintains that the impeller might deteriorate
in the antifreeze, especially, since most of the AF is Ethylene Glycol. IIRC,
the better one would be Propylene Glycol, but it is not easily available.
Btw. if AF drains, it is only better (you don’t have to worry about water
diluting the AF.

I am curious about why you advocate taking the impeller out. Won't antifreeze
drain out of your engine when you take the cover off the water pump?
