Frankly yes. I would rather see the warrior of light, through whatever means, benign or morally questionable, be fully rejoined, than not and in turn the story suffers in wasted potential and wasting peoples time and energy on it.
And by using such a plot thread, the missing fragments of the self, craft rich and textured stories that the audience would find engaging.
After all, the story has at this point all but abandoned the pretense of just sticking to the source at this point, what with the thirteenth, the first, azem's key, solution nine, living memory, the loporrits ship that lets them travel to other shards. And if we stick to the source, the loporrits are working on spaceships to travel out into deep reaches of space and we already had a taste of that with ultima thule through the ragnarok. As I personally get the feeling the writers are not very interested in Hydaelyn (the planet).
As Meracydia really only has two options in my opinion based on their track record, either its a Heavensward expansion where we explore it, or its a Stormblood expansion where we partially explore it but our attention is also divided on some other locale.
