I take it for granted there won't be any OpenGL support at all on the Apple Silicon version.

See documentation about porting apps to Apple Silicon here: https://developer.apple.com/documentation/xcode/porting_your_macos_apps_to_apple_silicon
OpenGL is deprecated, but is available on Apple silicon.
