Good features of this:

- Calls /git-upload-pack on servers in arbitrary ways to get trees and blobs directly and dynamically

- Once we find a git server that works we don't have to keep trying others

- Syntax highlighting grammars loaded on demand

- Binary blobs can be displayed as hex or readable ascii

- Images, videos etc are displayed when possible

- Buttons for downloading files directly

- Prioritizes specific user pages and specific repositories, not trying to do everything
