How do the Goaltenders in the Golem EX armor work?

Possibly mildly related to How does armor with Hull Points function against AVPL weapons?

The Vella Tacspec T2-F11 Golem EX comes with an RIP-A Goaltender that will provide DR reduction 5. The armor has Hull Points, which means non-Hull Point damage doesn’t really do anything. Do the Goaltenders intercept Hull Damage attacks? Or do they effectively do nothing unless the game introduces a weapon that bypasses Hull Points but applies against DR?
