The current entity render-distance (70 blocks) is extremely low and oftenly annoying, it makes it unenjoyable when playing on servers or with friends especially in games where you need to see players from far away.
I think the best approach for this would be in adding a toggleable bar which you could modify the entity-renderdistance with, this way everyone could choose the setting which works the best for their performance.
Java also already has this.
