That's sort of the way I see, yes gfx card drivers are terribly brittle but this is something the card manufacturers need to start looking into. We can't blame this all on the people trying to bring something awesome like WebGL which I think is crucial for the future of things like chromeOS. The browser vendor are aware of the issues and do a lot of checking (at least chrome does) of shaders.
