No. My argument is that (1) you and
@3catcircus are asserting that a new version of GH will cure problems that result from their being mutiple versions (in your case, disagreement over which is the best; in 3catcircus's case, contradictions between those published sources), and (2) I don't understand how publsihgin yet another version is going to be a solution to the problem of too many versions.
I also pointed to the Village of Hommlet.
I just pulled Treasures of Greyhawk - a collection of mini-scenarios - off my shelf.
The first adventure, for 4th level PCs, has a knight errant said to be of "level as PC fighter +1" and a 6th level gnome illusionist. An adventure for 6th level PCs has a 9th level fighter barbarian princess from the north. The adventure Terror in the Tropics, for 9th level PCs, includes a local tribesman named Malabar who is an 8th level fighter. On the Town, an adventure for PCs of the same level, includes an inn called The Weary Traveller where "a huge man dominates the common room", William of the Axe who is a 12th level fighter. There is also a party of 5 mercenaries, each a 6th level fighter; and is a band of four Nerrul cultists who are fighter/clerics of levels 5/4. In the temple of Kelanen in the same adventure the worshippers are said to be 5th level fighter and the 4 sentries 7th level fighters.
This is of course a 2nd ed AD&D publication, but it is quite consistent with the city encounter matrix in Gygax's DMG, which has mid-to-high level fighters (whether as guards, watchmen, rarkes, gentry, or just passing through) as common as dirt; and his patrol encounter rules - both in his DMG and the GH boxed set - which likewise are full of mid-to-high level fighters (and plenty of others too, especially on the GH tables).
My reading of all these materials is that the level of NPCs who are likely to serve as antagonists is set more by reference to the demands of play (mid-to-high level PCs need mid-to-high level antagonists) than by reference to considerations of "world building".
That may be a good or bad thing, but I don't think it makes GH especially distinctive as a setting.
