I seriously doubt that. Spore drive is no more or less fantastic in its basic assumptions, and if realistic portrayal is not relevant, then it can't be discriminated against on that basis, either.
"The geometry of spacetime can be made to bend for FTL" is as much charlatanspeak as "the basic structure of the universe allows for random points to be directly connected", be that by wormholes or conduits of other sorts. There's no evidence that any of this would work in practice - nor that it wouldn't. And what allows one to access "direct connections" is not known today, even in the most general sense. Might be tachyon bursts, spores, or magic words for all we care (and probably the real answer always will be "nothing at all").'
