Well, if you think about it, the Dark Energy plot can be just as relevant. Just about all the major tech in that universe runs on it, and it was partially established that it can adversely affect a system, as shown by that on section in ME2 with the planet you find Tali on. I'm sure they could have made it work with a little more development, but no use in crying over spilled milk.
