Having not used such a contraption, it always seems to me that the same thing could be achieved by leaning forward without one?

I lean forward (elbows resting on thighs). I've always done it. I never even thought it was a thing not to lean forward until I saw/heard advertisements for the Squatty Potty.

That, spreading cheeks when sitting down, and a decent diet means almost zero clean up.

It might be possible, but at least for me achieving the same position in a different rotation requires a lot of strength (due to gravity). And I can't poop while flexing half of my muscles.
