Leaving original coordinates for the quest pickups, but they can now be picked up at the delve entrance:
/way #2215 67.8 45.6 Skittering Breach - Hanging Parchment

Side note: Wowhead also lists Delver's Call quests for Fungal Folly and Kriegvall's Rest in the Isle of Dorn at the coordinates below, but I was not able to see these on any characters I checked. I'm not sure if they were removed, will be added later, or if there are any other prerequisites. I see parchment hanging in that spot but it you can't interact with it.
