Yeah, it'd be cool if they do!

Cool, ive read about Bazzite, but Ive also read about that Valve released Steam OS on other handhelds and that Valve could plan to make a general Steam OS release.

Oh yeah, a version of Steam OS that you can use on any hardware would be fun. Right now, there's Bazzite, it's pretty close to Steam OS and a lot of people use it to replace Windows on their other handhelds like the ROG Ally or Legion Go.

Indeed, Im excited to follow the news about a general Steam OS release.
I hope they keep it open for third-party-stuff.

I think it just boils down to the fact that Valve really invests heavily into giving the customers a great, all-in-one experience with Steam. It's a big part of why a lot of people refuse to use alternative stores like Epic: it just can't compare as an experience, no matter how many free games you're able to snag lol

Well, I think stuff like Custom Controller Configurations and an in-game API or overlay can be enabled being offline. Forums are Online either way, so discussions boards will make no difference in that regard. The same about dev blogs, they could be posted offline in-game, but that is up to the developers to do so and some do it this way.
Modding Workshops are Online, but the Mods get stored Offline - thats how it works already with Steam.
