The underpressure is a design feature (to minimize damage from leaks). I'm
willing to prime the system on those rare occasion that enough air gets into
the system to stop the flow in return for never needing to worry that a leak
inside the computer will short something out. If a hose leaks inside of the
computer the water ends up in the reservoir, not in the computer. The sound
of a leak is also pretty obvious.
