Yes, I also think this should be addressed in some way.
I understand this is something minor (fighting peasants is not something you frequently do in every playthrough xD), but giving basic weapons to peasants (nets, clubs, knives, wooden flails and the like) as OP said would be nice, or if that’s not possible, maybe at least change the encounters where peasants are the ones on the offensive (for example, replacing peasants with hostile town militia?).
