I'd be willing to bet that the game will be available in a compressed format from a repack site with no content loss. At least 30% smaller. A recent example that I just checked, Forspoken, Original Size: 103.9 GB Repack Size: from 63.6 GB
Before I had an unlimited connection for monthly bandwidth usage I would frequently download an already purchased game from the repack site and then have steam "repair" it. Shadow of Mordor/Shadow of War come to mind specifically. Saved so much of my limits at the time.
