It was actually made by a third-party game development studio rather than Microsoft.

Also the assumption that the culture of the Windows Terminal team is the same as the team building a flight simulator is a bit far fetched. Large organisations typically have very specific local cultures.

Rewriting stuff from CPU to GPU also isn't 101 game development. Both because it's actually quite hard and because not all problems are amenable to GPU compute and would actually slow things down.
