  Sure, as W3C only recommends a minimum contrast, no maximum.

In the end, this has to be a simple judgment call, based on aesthetics and which groups we're willing to saddle with slightly less usability. It seems like those preferring the lower-contrast text are the young, those with good eyesight, and possibly Dyslexics. Those who prefer higher contrast text are the older, or those with poorer eyesight.
  
  Fully agree. This judgement should however probably come from VDG, in particular from those who were involved in the initial design of the breeze color scheme.

Perhaps a less extreme change might make sense--a compromise midway between the status quo and my proposed change? How about this:

  This might work.
