I very much disagree with your critique - let me elaborate on why

The Spacebrat was EXACTLY, to use your words, "springing something so ridiculous on the players so suddenly (with 5 minutes of the game left), with no hints or any reasonably sounding scientific sounding explanation [about the Spacebrat] over the course of the last two games(if not three)", so your "argument" is as valid to criticize the original ending as it is to criticize this wonderful alternative - except there WERE hints at Dark Energy earlier in the 2nd game! Remember the Haestrom mission and the data reporting the sun in that system was aging way too fast? Remember how it played absolutely no part after you rescue Tali? That was supposed to be the first hint at the Dark Energy problem - of course in the released ME3 you never follow up on that reports because it was cut from the game! So much for your "argument".

About dark energy not being a threat in today's physics: Where did you get THAT from? It's a force we barely understand as is, we just know it is out there, and it's not that much of a stretch to imagine it could actually have some effect on the universe we are as of now uncapable of understading; since Reapers live for absurd long periods of time, maybe they have observed how it slowly but inevitably could destroy our galaxy (also, it is never implied OTHER galaxies don't have this problem, that is but an assumption of yours).

Since we also ignore WHAT it is the reapers do during their recurring 50k-year-long vacations, but I doubt they go to a deep space beach to drink eezo cocktails all day, it could also be possible that they "fight" this dark energy in deep space, barely keeping it at bay, and return to drink something else - organic cocktails anyone? :)

This harvest also allows for them to replenish their numbers, and harvesting the "potential" of humanity could very well help them in their fight against dark energy. Think about it. Better yet, read the leaked script of the actual ORIGINAL story behind the 3rd game - lots to learn from there.
