The vast, vast, vast majority of people are not able to find a person at Google to have that discussion with in the first place.
"Unless you are making apple SERIOUS revenue (think high6 to 7 figures) they will shut you down without even a response."
Apple tells you before your app goes live.
Look at the situation with PCalc and Transmit. Both apps which offered a killer feature, got approved by review and even featured by the editorial team, then pulled after having been on the front page of the App Store.

Neither of the apps got pulled. They got a warning. Whether the guidelines they were supposedly breaking were fair (or even existed) is a different thing.
In reality many times the first review is cursory and approved. They actually bucket you as a low-risk and wait for you to succeed before you might flag serious concerns and be removed.
If you are spending any significant time/resources developing apps, then you should invest a bit of time in networking. Go to conferences, and meet these people. They aren't that hard to find.
