It isn't about Shepard, it is about civilizations like Asari or Salarian with more then 2 000 years of experience with exploration of unknown space and colonizations of extrasolar planets but your suggestion would erase these experiences, techniques and technologies and return Andromeda colonists to era of first steps in space travelling. Even during era of games Council races and Quarians were sending exploration vessels on one way trip through space relays when they have to return by their own means across huge distances so is only logical to assume they already solved most major problems.
With little exaggeration your suggested space travel depending on oxygen and food from initial post would be like using nuclear powered aircraft depending on wind and sea streams.
Excuse me but it really seems you doesn't understand my point of view.
Yes, Asari, Turians, Salarians and even Rachni's have their own way to deal with exploration. They have a long experience in that. But I'm talking about the new game, MEA, and the point of view of the player.
Will the player stay in the back while everybody else make all the grunt work of the exploration and move only to kill every enemy in sight?
Or will the player take an active part of the exploration by finding the planets, searching something usefull on it, making the relay to open the path for the futur colon?
Yes, Asari and Salarian have an good experience of space exploration. But not on the point they know absolutely everything of a new galaxy at the second they set foot on it.
Yes, we have good-looking full of supersicence technological gimmicks spaceships. But they can be instantly crushed by a meteor, an high gravity planet or another solar disaster. And again, I don't believe they will found a planet full of apple trees : food shortrage may be an mortal problem as well (especially if you have a mixed dextro / senestro amine crew).
My point of view is : the player must have a feeling of unknown planet exploration and the Interstellar movie give a lot of clues about that.
But if, like in the trailer, the main job of the player will be to kill everybody, yes this is not needed.
