I lean toward Spock's good mood espousing the 'significant for any species to actually do on its own' argument with a little 'crazy genius in garage' thrown in for good measure.
I'm still relatively certain that the original TOS intent was that Earth, for the sake of 'Metamorphosis' in the person of Cochrane, invented 'the space warp' and the Federation/Starfleet was just a benevolent Earth empire that spread through the galaxy, taking warp along with it. Tyler's line in 'The Cage' about the time barrier is, to me, almost certain proof that warp was meant to be an Earth-devised quantum leap of this nature.
In regard to other races, I also feel pretty sure that it was meant that the Romulans never had it (though I think the original draft for 'Balance of Terror' meant to suggest that they did now, but stole it from Earth - again, another victory for Cochrane's engine.) I also feel pretty certain that what the Klingons were meant to use, while similar, was not meant to be 'warp drive.' And, I also believe that the writers didn't put a lot of thought into how everyone else achieved interstellar flight, but it stands to reason that there were probably other ways besides warp drive that didn't bear lengthy examination or explanation.
The sheriff doesn't explain how his pistol fires, remember?
