I for one jhave been seeing some evidence -- the notification to site owners about possible bans when they have infractions of the guidelines, for insatnce. At Boston PubCon this year Matt Cutts and the sitemaps team also talked about plans to enhance the Sitemaps program to allow for more feedback and 2-way between Google and webmasters.
How well this is executed certainly remains to be seen, especially in the more public commentary. For some reason (it just seems to come with scale) it's very challenging to any big company to avoid spin and keep things pared down to straight talk.
