Perhaps, but "WIP" is referring to Windows Insider Program, I'm pretty sure - people who've signed up to beta test.
It kinda makes sense to want to know who is doing your testing. I have to login to file my test results (I'm logged in right now). My whole PC doesn't get logged in, so that's different. But, my test involve uploading potentially identifying information (when a bug is found).
It's a bit of a step to say that it'll be universal across the sold versions. Though, as memory serves, you'll need an account to activate any MacOS and I think I needed one for my iPad that I don't use. So, there's precedent.
Not that that'd surprise me to see Microsoft do that... Not even a little surprised.
