Don't modern versions of Windows do the same? For example, I clearly remember that the Windows 10 installer first launches a Windows 7-like environment.

Aren't all modern (>xp) windowses just NT6 under the hood? Is there such clear delineation between 7 and 10 for example?

They're all NT, though I'm not sure how you mean "NT6"; XP was NT 5, Windows 10 was NT 10, and I think 11 is 11.

NT 6.3 was Windows 8.1, apparently.

Incidentally, this is why most drivers broadly support 2000/XP (NT5), Vista/7/8/8.1 (NT6), and 10/11 (NT10) in those specific groups.
