...but apparently 810 years wasn't enough to make it viable for an organization of over 150 alien species working together?
If something better than dilithium were practicable, wouldn't somebody have come up with it in 810 years?
Apparently not, since in 2150, there was nothing better than dilithium, even though many folks had been toiling on it for 810 years. The same in 2265. Or in 2370. Time doesn't appear to be of any help there.
So the only real question is, does the failure to make any headway stem from nobody wanting anything better (the reason cars have not evolved a bit in a hundred years)? Or from it just plain not being possible to make headway on this matter?
If stuff that works in a lab were practicable, it would most probably see use. If it sees no use in 2150, there's no real reason why it should see use in 2380 or 3190 or 4711, either. In a universe that catered for improvement, dilithium drives would be mere practice wheels for young civilizations that look up in envy at the adult majority driving around in their coaxials. Instead, coaxial drives are about as common as rocket-powered cars are today: perfectly doable, and indeed done on occasion, but really not worth the hassle. And only truly superior lifeforms such as maples work on solar power, and only the Borg and the Voth travel at transwarp - the latter having had tens of
millions of years to get it right.
I really don't see a coalition of powers enjoying any sort of an advantage over a diverse bunch of competing powers; quite the opposite, really. But before the Federation came along and slowed down all development, it was already at halt from all the fierce competition between the powers, suggesting there simply is no room for improvement in mortal warp.
