The chart is to separate theory from practice, because in practice, a lot of state tracker/driver combinations don't work right or aren't conformant. I wanted to make sure that people were aware of deficiencies and bugs in implementations; in particular, I'm kind of tired of no good way to test OGL conformance and I would rather be embarrassed by a status page than annoyed by bug reports.
