On a local install, I changed the system supported line to
this.systemSupported = /dnd5e|pf2e|sfrpg/.exec(game.data.system.id) !== null;
and dragged a large-sized Starfinder creature onto the scene. It was auto-sized to take up 2x2, as intended.
Looks like SFRPG is supported out of the box. It's only your regex stopping it from working.
