Yes, that explains what Humans bring to the table: sheer, ill-informed, unbridled, un-jaded, undistilled, optimism.
It also explains why Voyager sports bio-neural components that can't handle cheese, why 1701-D is comically oversized compared to its crew compliment, why outfitting the entire Federation fleet with recycled Borg tech got the green light, and why bridge workstations have a failure mode that kills the operator with heavy-metal concert pyrotechnics the moment it's shaken too hard. Nobody told them they couldn't do that, so they did.
The alliance with the Romulans during the war was tenuous at best. They never could have swung that. At minimum they would have needed to share the tech.
I know it wasn't, but in my head I always figured this was the cloak of the cloaked minefield in front of the wormhole. Then the dominion couldn't just fire a torpedo and blow up the grid. That made the minefield make more sense to me.
