No, read the Q&A again, it's full unlock:

Q: Will the difficulty of turns 1-5 be eased? And will the weekly lockout be removed?
A: Since we’ll be adding the second installment of the Binding Coil of Bahamut, which exceeds the difficulty of the first installment, we'll be removing all the limitations on the first five turns of the Binding Coil. The weekly limitation will also be removed, so you can take on the first five turns as often as you like
And in another separate Japanese interview, it is also confirmed that myth tomes weekly cap will also be unlocked. Basically all i90 related content will relegate to Darklight status because they will raise the new item level cap with new set of BC loots, Leviathan weapon and new tomestones.
