Droid Mission on Vulcan is it an Easter Egg? I missed it twice!

About a week ago, I replayed the vulcan mission for the 3rd time and accidently found the droid mission

Looking at this link and the replies I relised I wasn't the only one who had missed this FPS.

When you leave the hanger and are in the corridor you have the door on the left that leads up to the "Control Room" and opposite that door "Engineering", a somewhat obscured door, that leads down to the supplies room, where you can control the droid. Quite fun really, very short. Seems to be a practice run with a droid. Maybe I missed a section in the main game.

You don't need to complete that mini mission, it maybe an easter egg? Always thought the Carrier section was very short, shoot 3 droids, job done carrier is yours.

I had always wondered about that bit...

You can eventually get the droid to open some door somewhere or something like that, but I think I didn't find anything to do after that.

I'm all for easter eggs in games - but it would be kind of nice to have some obscure benefit to them :)
