My point is that in the original ending, we didn't really have any solid way of knowing if the destruction of the Mass Relays would be different than what happened in Arrival, since Shepard doesn't really seem to care, and doesn't even bother mentioning it. I think we knew that the writer didn't intend for that to happen, but the narrative provides us with very little information. Thus, it was changed in the Extended Cut to say that they take a lot of damage.
