> windows 2000 wasn't widely used as a consumer installed OS

But Windows XP, which came out in 2001, inherited everything from Windows 2000 and more, and was used extensively for gaming.

Absolutely and first iterations of steam hardware survey showed mostly XP users, but still 5-7% win 98 install base, which they maintained compatibility with for quite a while, that's just to say that I can see why they might not have used those specific windows APIs at the start.
