I would assume the issue is all the variation in different distros. Plus the driver/hardware combinations. While some setups would just work they don’t see it as worth spending the time doing the validation/patching required. The steam deck is 1 device to test, with a single software stack. Much easier to target, and with a known customer base. Which brings up the other issue that they would be unlikely to make their money back on a general Linux release. Companies have cited this as a reason for not doing macOS releases in the past and based on the last steam survey Linux usage is in a similar ballpark (2.6% vs 1.8% for Mac ).

Despite all this I think it’s still a move in the right direction.

Valve released a runtime specifically to combat the variation problem. This allows developers to target a specific runtime and Valve will make the software stack work with as many distros as possible.

On the other hand, that stack can only contain so much, and a lot of Linux bugs involve sound subsystems, GPUs, and compositors/X11/window manager configuration issues. You can't quite target the Linux runtime and assume everything will just work, but at least you don't need to target specific versions of glibc and libxml2 anymore.
