So, after a bit of research, it seems you're not completely off your rocker and no, I did not read whatever was at the link you pointed to. The plain fact is, that if you manually create a USB installer, you may encounter the problem you describe with the installation media partition type being a problem, HOWEVER, that is not how media should be created ANYHOW so it's a moot point.
There is NO reason to not use the Windows media creation tool, for ALL installation media creation (Unless you are doing something exotic, and that is not what THIS discussion is about), in which case this problem does not exist. You will never encounter this problem with the partition type issue on the installer media if you use the Microsoft creation tool. So, you are right, but you are wrong.
