I don't see any reason to. If you limit the volume of water emission from the watering system you will limit the pressure loss. You don't want water flooding the area, you want it to have time to permeate the soil. If you are applying water slowly you can leave the water on 12 hours a day. At 2 GPH per tree even that is a lot of water.
One of the problems I have with the soaker hoses is the water emission rate is built into the hose. There is no way to throttle the output to suit your needs unless you turn down the pressure, which starves the far reaches of the hose of water.
