Seems like a lot of people want to turn Bannerlord into an RPG.
IMO, the game already has needless RPG mechanics like loot modifiers ("cracked" etc.), smithing, playing board games with lords.
M&B for me is a third person strategy game, where you control a character. It doesn't need traditional RPG mechanics.
That said, adding detail to the game world to make it feel more alive would be great. It just doesn't need a bunch of RPG side-activities and mechanics.
