Just the pressure in hoses, coolers, O rings. They are all placed under more stress that can lead to a failure.
There is really nothing to be gained by raising the pressure. You can't force more oil through the big end bearings. They have there own, hydrodynamic oiling system, that relies on the rod moving up and down on the pin to pump the oil up to the top of the pin. More pressure won't make this work any better.
