I will freely admit that it may have been centuries ago that the theory was laid out and only the MAlign paid attention to it because it knew something no one else did (probably because they suppressed it). But more likely than not, if it his had been the case, they'd have abandoned a research proposal that hadn't panned out in centuries.
So it's far more likely that the initial theoretical breakthrough is no more than 50 years old and the last big engineering challenges were only overcome 25 years ago. Until this had been show to be a viable alternative, it would not have been made their central plan.
It might have been there for some time. Theoretical papers, maybe from some physicists in some backwater university, but no practical appliance. Similar to some current pyhsical papers suggesting the theoretical possiblity of implementing FTL drives using artificial gravity, or negative masses. Theoretical papers, nothing more.
Why should someone develop some "alternative" propulsion system which is less energy efficient, provides far lower acceleration rates and doesn't work within grav waves, when impeller technology is established, proven, "cheaply" available and far superior, as everyone knows?
