I don't think he really explored it all that much though. Maybe if you really tried looking into it, but I think he took a very simplified view of the concept.
I still just found it all around nonsensical and silly. It was fine if we are taking on Jane as an individual but together with Thor himself and as part of his overall mythos I just could not buy into it and how characters responded.For his story to work he needed to craft it in a way that allowed Odinson to hand over his name. He does it pretty quickly but not immediately and not without a whole issue examining the issues. The argument was had in that issue. No point still arguing about it now. It was a name, turns out it was more than just a name. It was an idea and a not only that, it was an idea manifest in a mortal form.
It's comics. "Canon" is always dubious .Even making the claim now is pointless. Aaron decided, Marvel rubber stamped it. It is canon now.
I mean, she's got his blonde hair, way of speaking, and the personality and attitude to match. So in that form she is definitely Thor.
Jeez, I wonder when Thor got named if they were expecting people could just pick up his name and archetype with just a grab of a hammer .
I think that's true of Aaron's interpretation of the character, but for me, looking at the wider character of Thor, I don't he placed as much value in his worthiness and identity in Mjolnir or was as obsessed with hammers.
It's kind of interesting to think that in relation to the Asgardians considering they're immortality and long-lived lives.
