I personally don't miss trying 2 or 3 or more sizes to finally find one that fits the chainline. Especially since the square taper press fit makes it feel like there is a limit to the amount of times a crank can be installed and re-installed. Maybe not.

I will say that when I fit an old Campagnolo crank in a 1x to a new IRD bottom bracket that looked like modern art, it was cool. I might have enjoyed calculating the ISO vs JIS mismatch.

These hollow axle cranks - I have them from 4 or 5 major brands on various bikes - are just better. Smoother, stiffer, simpler.

I don't think you can fault the design because you got the wrong part.
