The issue with that is that it appears as if the 1.0 echo has been retconned rather than being ignored for its inconvenience. Keep in mind I've never played 1.0, but from what I can gather from what I've seen in this thread that most of its unique parts, like interacting with the past through the echo seems to have been dropped started in ARR. And its not like this doesn't have a precedent, during his recent Radio Mog Station interview Yoshi-P stated that as of 3.0 the devs had completely rewritten the Ascian lore from 1.0 and ARR. So its not out of the realm of possibility it was dropped like Gelmora and Silvertear appear to have been.
