The thing will also be a weapon of mass destruction of plannet cracking potential, one "parking accident" away from making planets uninhabitable.

On the other hand a civilisation producing such things should hopefully be technically immortal with lots of distributed backups for each individual potentially affected by such accidents & resources to fix up any affected infrastructure. So still, totally worth it, go fo it! :-)

(Less advanced neighbors might still be a bit on the edge, so please be considerate.)
