Disappeared Ancients

From the update notes for revision 1.0:

Non-Transcendent Ancients: Iris, Khrysos, Pluto and Thusia do not exist for players who have transcended.

Does anyone know if they're still available before one's first transcendence? It's just an academic point, really; anyone who puts off transcending long enough to actually use them is, frankly, doing it wrong. I'm just curious.
