The new OOBE screen, while it looks really good is infact way too buggy to be currently usable. Especially when trying to create a new account from within the setup screen.
Moreover, if someone is using a static IP configuration instead of DHCP in their router, they are doomed when they try to set this up because no matter what you try, you can't escape the MSA sign in and if you can't connect to the internet at the OOBE, you just can't sign in...
It was somewhat a mess in Windows 10 (somewhat, because we still had option to local sign in), it got worse here with 11..
