Main disadvantage is too much area for weeds to grow. Too many weeds or filamentous algae growth will limit your use of the pond (fishing - swimming, etc.). Too much of this "weed" growth usually results in use of chemical treatments and these treatments often suppresses the periphyton growth that contributes to the pond productivity and fishery and negates the optimum fish growing benefits of the littoral zone. One has to try and find a median somewhere in between all this.

Hopefully new technology will produce species specific weed control. I hope. I hope.
