Most of the aliens/humans in the OT had names in the script or for their costumes (4-LOM "For love of money", Barada, Klaatu, Nikto, etc...), so EU aside they're quite possibly being lazy.
Again, we have at least one other named X-Wing pilot so far (Ello Asty). I find it much more likely FFG just didn't have access to information like the names of background pilots at the time they were developing the core set and the expansions.
