Well, streamlining that section of the story would essentially be the same thing as skipping it, except that it would force everyone to miss it rather than just those who want to.
The problem with the pacing in that stretch of quests isn't that there's too much fluff (which could potentially be streamlined away). It's that there's no fluff at all. Every* quest is densely packed with essential story and world building details. It's great if you're alternating that with still doing other activities to vary the pace a bit. But if, like so many players now, you're trying to bulldoze your way straight through all those quests in a row, it's quite a slog, simply because it's a lot of story to take in in such a short time frame.
* Nearly every quest, anyway. All but one, so far as I've seen. I'd heard so many requests for that stretch to be shortened, that I've been going through it looking specifically for places that could be shortened. I'm on the 68th of those 100 quests, and so far there's only been one that could maybe be cut out or shortened without major damage to the storyline. (Ok, and there's been one other whose necessity is more about pacing than story. It's a simple kill quest included where it breaks up what would otherwise be dialogue after dialogue after dialogue after dialogue.) And while it's true that I haven't finished all those patch quests yet, with the excitement of the story rising towards its climax, I really doubt there's going to be any more streamline-able content in the remaining third than there's been in the first two thirds.
