The oldest and newest versions of each loader are installed by automated tests against the real services. Those tests check that the game files are complete, but they do not start the game.

Apple Silicon#

Mojang publishes no jre-legacy for Apple Silicon, so Modsmith installs older Forge versions with a newer Java. Whether those old versions then run is decided by the official launcher.
