Yes, we have never encouraged/discouraged the arm flapping. If anything, we mirror it and encourage dd to express herself. The more easily she can express what she is thinking, the more the arm flapping has diminished. Actually, I miss the flapping. It let me know shat she was thinking was really important.

I recognize that the autism spectrum is rather arbitrary. As long as dd is happy, connected, and communicating, it doesn't matter to me if she is on or off the spectrum. She is herself first.
