Sorry, I had conflated Windows NT development with development of 64-bit Windows as told by Raymond Chen: https://learn.microsoft.com/en-us/previous-versions/technet-...

Raymond also says elsewhere that most WinNT engineers did development on i386, but doesn’t explicitly say what time period he is describing: https://devblogs.microsoft.com/oldnewthing/20250513-00/?p=11...
