It’s relevant to Win11. Win11 is supposed to be going SaaS. So if you want to stay on Windows but don’t want your OS to be SaaS…

Edit:

Having said that, it looks like this may not be as much of a lock as I thought. So maybe I’m talking out of my butt.

I’m simultaneously embarrassed by that if so, but also kinda happy that my days of running Windows are so far behind me that I’ve stopped subconsciously paying attention to MS news enough to be wrong about something like that.
