The only reason they are in the Warehouse is because (What i think) The inventor or Warehouse agents/regents deemed it either too dangerous for mankind, not ready for people just yet or it was mothballed and stored in the Warehouse.

So given that, the only reason i see with Artifacts and the Gadgets stored side by side is just they can pose a threat, like any other artifact in the Warehouse with little or big consequences.
