This is probably to the chagrin of the 3.x Warriors of Darkness, who had to kill themselves just to land on the Source.

Also it must not only be us who will be able to travel between the First and the Source and back, because we are shown what may be the primary hub town of Shadowbringers, and primary hub towns have thus far always have Marketboards and retainers. So we must be able to summon our retainers across Shards, and when we buy an item on the First's Marketboards, we will presumably have to pay interdimensional tax.
Or those things just keep on working for the sake of gameplay mechanics (Time-bubble events, Khloe, Marketboard, retainers), without really being affected by the story, or simply handwaved with a comment on the side (see: Crystal Braves in Ul'dah).
