They're building out a comfortable development environment for steam machines. Which is great. When proper well documented tool are available, developers are less likely to shun a platform. If there exists a some GPU memory profiling software (not that a team couldn't competently create their own system) and keyword completion for OpenGL calls then I might consider switching over to Ubuntu for development myself.
This is, of course, throwing aside all DX vs OpenGL arguments based on feature support (which I'm not really familiar with at this time).
