When you control your summoned and press shift-g for level up it goes into the adding stats screen and you have a shitetonne of stats to distribute for whatever your in control of - their main stats are already maxed, but you can pump a hellova lot into dex/cunning.
I'm guessing your not sposed to be able to do this, and when controlling a melee summoned it would probably make quite a difference when you can max out their stats (and have points still remaining).
Not a game breaker, but interesting.
