Possibly the best news of 2025 to close it out.

Someone on the Steam subreddit was asking for Valve to make a #SteamOS phone (seeing how the new VR headset is Arm but also playes x86 steam games). And I thought "Hey, I've already got #PostmarketOS on a phone. We know Valve is using some 'FEX' library. How hard could it be?"

As it turned out, remarkably easy. (Though, it helps that someone already wrote a guide for it: https://wiki.postmarketos.org/wiki/Steam )

Pretty sure it's a YMMV situation, but my milage was pretty good.
