It's possible to differentiate GREASE ECH vs real ECH when the public_name gives it away, but any deployment that uses an inconspicuous public_name should be able to achieve indistinguishability. I see that goal as important because it reduces the likelihood of ECH blocking, which in turn increases the likelihood of ECH deployment.
