It didn't have to be curated due to the time. It was the default throughout the books. Most of the Alpha series modules were set there. It was the setting for AD&D. I would argue the gonzo races that 5e allows now, with Furries, Ninja Turtles, and everything else is not the tone intended for Greyhawk. Its fine if people want to play those races (as long as I'm not the DM) but using those races suggests a much different tone than is suggested in anything but Eberron. I have no idea what Wildemount is like, but if they created that they should have just used that as the default 5e setting. The creators from everything I hear made it work for the modern flavors.I see no point. Greyhawk has never had prohibitions on races in 1e or 3e and was never curated prior. The only curation I've ever heard for Oerth comes from grognards who can't accept anything that Gary didn't write as canon.
Now Forgotten Realms is less curated because they unfortunately made that the default setting.
