There was talk of changing estates so that they are based on number of peasants, rather than percentage of region. If this was done, you could code estates to have a minimum number of asked peasants. Therefore you couldn't create an estate that gave someone 3% of a !@#$ty bad lands region. The lord then couldn't create lots of little, worthless estates. You could code in an efficiency penalty for too many tiny estates, due to administrative overhead.
