I'm on Windows 10 at work with four displays (2x 27" and 2 x 23") and Windows can't even remember the position of app windows after closing and re-opening the app immediately, don't even have to unplug and replug a display for this it to exhibit this amnesic behaviour.

Isn't it up to each program to ask for its windows to be displayed in a particular place?

(Not up to the OS to override programs and show them where it thinks you want them; “how do I save window position?” used to be a popular question for Windows dev).

Yes, and Windows will try to put an application window where it was if the program asks Windows to do that. If I am remembering correctly. (Big "if")

Why the onus is put on each application to turn this on is not clear to me.

Why wouldn't it be?

OS X will remember & restore a pos with a matching title in a certain app[bundke identifier]

WinApi provides calls to do the same which iirc goes in the registry, but it's not automatic.
