I'm going to look at this as a ye ol' 1.0 player and I have for one saw the good and bad of the potions, but in a very simple term, in my own point of view, if they do what we 1.0 players had to do, it won't be all that bad.
What did we 1.0 players have to do?
Well, if you were lvl 50, like myself, you did the content as lvl 50. This meant you flew through ARR's material fairly quickly because you could pretty much one shot whatever. Given the fact of now the Unsync (which we didn't have), you can get with your high end friends, if not flat out solo some dungeons.
Personally I believe the best way to handle the Jump Potion and what I hope they will do is like this. You still have to do the MSQ, but because of your sudden "level up", you can just fly through it. They get to see the story (if they want), take on the content however they like, and still learn things while having that lvl buffer.
EDIT:
I saw how they are handling it in your post above, so they are sort of doing what I figured they might do, but still going to leave this as my own opinion, if even slightly invalid by the recent information.
