This could be the case, or could not be. They shared a post on Reddit 19 hours ago from their official account, and I thought it might be nice to share that here, at least to spark some discussion.
They simply shared a post titled:
Shall we? 📦💿

I’d rather see them just list the ISOs so we can burn them to disc ourselves. These are fun, but niche. Listing an ISO isn’t far off from what they regularly do.
I mean that’s also woefully outdated. Just use the installers they already provide and put them on a thumbdrive, there’s a solid chance that’ll last far longer than a burnt disc would, too.
Optical storage is much cheaper than physical storage at the moment. If I wanted to back up my entire steam library, it would be less expensive to do it with a mix of Blu-rays and DVDs. Blu-rays are also good from 10-50 years, with archival grade good for up to 100 years.
Now, yes, I can just burn the installers to the disc, so that’s fine, but I’m talking specifically about them released big box games, where I don’t necessarily want the game, but I do want the launcher/installer experience as it was when it was first released.
