I do get that, honest. I also appreciate that the show can't - and shouldn't be - constrained by 50 years of established guff. That would be disastrous, and besides no Trek movie, series, season or individual episode has ever felt obliged to do so. There are episodes of Voyager where characters assert the complete impossibility of things that actually happened to them just the episode before. (I watched an episode just tonight where the Doctor and Janeway discuss her hypothetical reaction to the supposedly unlikely scenario of Harry Kim meeting an alien girl, falling in love and wanting to leave the ship... an event that had occurred in the previous season).
It's just... even if turns out to have inescapable unworkable side effects (which it will), you'd think the existence of instantaneous spore-based travel might have come up again independently in a society of scientists and frequently desperate explorers, and the dozens of alien races and rivals we've encountered, over the subsequent 100+ years the various shows have covered.
Instead of just being discovered once by Stamets and his pal, and then hushed up.
