If so, why didn't the rest of Starfleet do so during the Klingon War, particularly during the nine months Disco was in the Mirror Universe when they would have desperately needed the tactical advantage since the Klingons were conquering 20% of the Federation and establishing a foothold in the Sol system itself resulting in the Federation relaxing its morals so much that genocide itself was being authorized by the government?
The Federation were busy trying to survive, they were getting their butts handed during the Klingon War.
They have more pressing matters than to go Tardigrade hunting.
Because it wasn't possible. A fact that continued to be the case as far into the future as the 32nd century. Or even the 33rd, based on the epilogue of Disco's finale.
I don't know how you get it wasn't possible.
The Spore Drive was amazing, yes.
But getting it mass produced required genetically modifying yourself so you have Biological Navigators.
Remember, the UFP have been very touchy on Genetic Engineering, that hasn't really changed all that much in the 32nd Century.
Given the requirements, I could see why the UFP opted to go with the "Pathway Drive".
No need to violate their own laws to make it work, even if the Genetic Modifcation didn't really give you super powers or enhanced anything short of not being able to be affected by changes in the "TimeLine".
Man that feature would've been pretty amazing during the Temporal Wars now that I think about it.
That Genetic Enhancement could prevent Time-Line changes from screwing you over in a Temporal War, that would be pretty OP.
