You're right, 2nd edition had quite a few early on in the Greyhawk Wars era, but so much of unattributed 1e material was from Gygax's Greyhawk it's hard to get a handle on what was and what wasn't.Greyhawk actually received a lot of product support during the second edition of AD&D. More actual support than during first edition believe it or not. Third edition had at-least four Greyhawk products. The only edition that no paper supplement or hardcover book was produced for Greyhawk was the fourth edition.
With the few publications since the late 90s I don't believe most teenage or 20-something D&D players have had much contact less actual play in the Greyhawk setting. That's not to say I wouldn't love to have the setting back in publication, but I don't care for much of how settings are treated recently either.
