For the record, I don't think these modules should exist for the same reason my CMDR's focused efficient (thanks legacy secondaries!) TLB PAs shouldn't exist.
In my opinion, everything that exists in the game should be fungible, or at least be able to be acquired, via some means, by any character. I don't like exclusives (and yes my CMDR has a Cobra IV, and reduced insurance, and bunch of other stuff no one can currently earn, via any method...I would gladly see it all removed, if it meant for a more equitable game) and I don't like grandfathered/legacy equipment.
It's ok to have rewards, even significant ones, but to reward items that can neither be transferred (either through sale or theft), nor recreated, rubs me the wrong way.
