it didn’t seem to have an answer for why the Federation didn’t use it later.

Well, you need to either find and enslave an exotic space tardigrade in order to navigate the network, or illegally splice said tardigrade’s DNA into your own.

And even then, navigation is pretty challenging, and can result in accidental time and/or interdimensional travel.

And a malfunction has the potential to destroy all life in the multiverse.

And both ships that had the prototypes installed were lost within about a year.

Take your pick, really.
