I keep getting these missions, and I keep checking the forums to see if anyone's EVER reported that these have become the awesome story experience they have the potential to be. Alas, I've yet to hear that. Seems like every thread ends with some variant of "It takes a lot of time for very little satisfaction (or reward)." It's really too bad. They have SO much potential ...especially when something like that could potentially be sourced to the community.
For myself, I'd do these in a heartbeat if only they granted an Engineer favor or something. At this point I've engineered every possible module and weapon for half a dozen ships, worked every engineer up to G5, and done countless weapon mods. I've NEVER yet gotten a corrosive or incendiary MC roll, and only seen two scramble spectrum effects for dozens of modded pulse lasers. And I've never seen a roll that granted an engineer favor (do those even exist anymore?) I'd go to great lengths to earn engineering favors at this point, rather than having to continue burning all the mats needed for every G5 mod attempt!
