People are using iPad OS features on their iPhones

I have an 11" iPad and the screen still feels too small to use windowed apps. It gets very cramped very quickly.

I can't imagine trying to do that on an iPhone. Surely it's useless.

What this does do is reveal the fiction that "iPadOS" and "iOS" are separate. Clearly not.

It might not be super practical on the device display. But with external display and keyboard/mouse this becomes much more usable.
