The main point of 32-bit Windows 10 wasn't to make it run on non-64-bit hardware, it's that x86 processors can't run in 16-bit mode if they were booted in 64-bit mode, so if you've got an old 16-bit Windows/DOS/CPM app that you've absolutely got to run natively instead of through DOSBox and have to use modern Windows instead of an older version, it needs to be 32-bit. By the time Windows 11 released, Microsoft had decided that nearly no one still wanted to do that anymore.
