I can't think of one single reason I'd want to go anywhere near Windows 11. If a machine came with it preinstalled I'd uninstall it in favor of 10 and call it a day. There is nothing compelling about Forced Obsolescence: the OS to me.
I think it was only available on some particular Insider builds of Windows 10, not the general releases. Cynical take is obviously that they discontinued support precisely to entice developers to migrate to Windows 11.
