Only initial thoughts are why in their right mind are they using windows on a handheld device
Windows because it will cost Framework or whoever it is a lot to do it Valve style - coming out with your own distro, support it and yeah the proton issue. If it will run only Linux games, that market will be minuscule.
I mean, you’re not wrong, but I’m pretty sure Valve would allow other companies to download SteamOS for their own platform. You can already do it yourself for free.

Not to mention the main functional part: proton doesn’t only work on SteamOS
