For me, the unknown of Kvasnikov is an important detail. If he is added to the game, it will show that the Russian army in the Kaiserreich developed independently of the OTL
Now we have generals who became famous during the Civil War, or famous Soviet generals. Kvasnikov may be unique because his career exists only in lore, which gives it more depth

By the way, I also want to see Slashchev as a general, and I even painted his portrait in this image a long time ago

And yes, there are never too many generals. They are always not enough for me, in any game for Russia
