After the cat was out of the bag and they were ancients. I think this is the best way they could've done it. I really don't enjoy mysticism revealed either, we didn't need to touch them, but I don't think their godly virtue got hampered in any way. They still did their duty for 12k years was it? And still continue to guide mankind and their prayers for the betterment of the star directly from the lifestream.
My main fear was that they were going to destroy the whole religious system in Eorzea and they didn't.

I agree with some people in this thread, that it's just a sign of them wanting to write everything from ARR off for a new storyline to begin. EW basically felt like two expansions packed together cause "We need to wrap this thing up". I HOPE the rushing will be worth it in 7.0 I really do and it wasn't just to get FFXVI out to the markets.
