Ha, I asked this exact question to @Polare yesterday and got this response:
Question:
How should we convert 1/e cloaks/banes (ones through ritual flaws or TP, not ones from True Empowerment)
Are /ever cloak/banes being removed from the standard ritual flaw list?
Answer:
Existing flaws on a batch should stay as-is (other than True Empowerment ones, as you note).
There are no changes for Ritual Flaws. Especially since each chapter can (and often does) do their own.
