OT - The Napoleonic EB (Sort of)

[A Terribly Harmful Name]

To answer your questions, a "grognard" is:

Grognard is French for "grumbler".[1] It is not necessarily pejorative and is sometimes used as a compliment. Historically it meant a soldier in Napoleon's army, particularly a member of the Old Guard.[2]

"Grognard" came to mean a veteran wargamer in the early 1970s.[3] It was first used by John Young, at that time an employee of SPI, and subsequently popularised by Strategy & Tactics magazine.

From wargaming, the term moved to role-playing games where it was used to mean someone who preferred older-than-current editions of a game (for example, a person who stayed with first edition Dungeons & Dragons even after the second or third editions were released).

Nowadays, in colloquial usage, it refers to someone who has been involved in a hobby or pastime for a long period, particularly those involved in earlier phases of a now-popular hobby. It is still most often used with reference to wargames or role-playing games. It is primarily used as a pejorative term for gamers who refuse to try newer versions of a game, which they often see as an unwelcome rehash of the old game.

Third, that's a question which is best answered in their own forums. In my experience, everything from the order of battle to the specific command and individual unit intricacies shows variations between factions to represent their differences and strive for historical accuracy (they're not just carbon copies of one and another unlike in ETW), so I would not be surprised that such factions are absent due to the lack of time to implement them satisfactorily.
