And the Sartarites themselves (not to mention their Lunar overlords) aren't above "moving around and renaming clans," or indeed tribes -- just look at the differences between 1610 and 1621 in Walter Moore's old maps:

Or the Colymar shenanigans described in "King of Sartar" and mapped out by Greg here:

There's definitely a place for maps showing borders at a point in time... it's just that, given the depth of Glorantha's history and the variety of games played there, that place probably *isn't* the main pictorial poster maps.
After all, some of them might not show the boundaries of the old Kingdom of Tarsh correctly (incorporating Lunar Tarsh, the Exiles, and the Far Point region), and *then* you'll have some difficult explaining to do, when King Arim returns from his ancient resting place... now, you wouldn't want to make him angry, would you?
