Since they haven't given any details, anyone's guess is good here. Prior to the international release of WFaS, the few communiques from the devs indicated that they had "taken note" of the community's propensity to create real-world/historical mods. With the relative lack of enthusiasm from the established M&B players expressed toward the international release of WFaS, they noted that they learned what type of games players are more interested in. Whether that was meant to reflect on "standalone expansions" using the current engine vs new games, or a historical setting vs Calradia is likely quite debatable.
I'm not certain why the reception to it was tepid, but it might have had to do with the buggy condition of it's first release? But there are elements and features and bits of history in there that are really cool... It's a nice change of pace from the more familiar setting of calradia. Also, thie WFAS world feels a bit more alive, gritty, real, etc. OF course the cities were done in a rather rudimentary way, and some details were wrong, etc etc.
But take note of all the mods for M&B that are NOT historical as well.... there are as many if not more mods out there that either enhance the existing campaign, or incorporate elements from other fictional worlds, from middle earth to...halo. Some of the most popular were historical, but not all of them- diplomacy comes to mind as being a pretty widely-loved mod too. People DO like the Calradia setting.
I don't think it's necessarily that people like making historical mods... the fans love making mods, full stop.
The problem with the fans who want historical settings, is that they are too small a number for sales to justify investing much money into development. Furthermore, people that are interested in historical simulations want them to be as historically accurate as possible. This presents a few problems:
1) Not everyone agrees on what is historically accurate. Not even the people who have spent years studying just one period and culture in history can agree on all the details... and those who disagree will tend to have a disproportionately negative reaction to details that are, in their view, "wrong".
2) historical accuracy MUST be sacrificed to make a fun game. Either that, or one must suspend disbelief or simply ignore major details in order to make it work. Take mount and blade, for example:
Lets say that you ride into battle with no armor, and are attacked by a group of bandits with bows. You take a couple arrow hits but are otherwise fine, you kill off the bandits, and then split the loot. That is what happens in M&B. In real life, you take a couple of arrow hits, and it's all you can do to just stay on your horse. After the battle is over, if you didn't die from blood loss, you are very weak and need immediate medical care, probably involving surgery. Since 12th century medical care basically amounts to applying a moss poultice to your wound and forcing you to imbibe some herbal concoction, your wound becomes infected and you die in misery.
I think fans like having some make-believe elements around.
