True, but not a 1:1 comparison, because Classic Mac OS windows were much better at staying where you put them, even between sessions. John Siracusa wrote a lot about how this was missing from Mac OS X: https://arstechnica.com/gadgets/2003/04/finder/
People also didn't regularly plug classic Macs into external monitors, changing the screen resolution temporarily.
For this and many other reasons, I just don't think the paradigm would work today. It's philosophically smart but limiting in too many other ways.
