Could you clarify a bit more what you mean by "Domain Fronting is why ECH exists"?

Because even with ECH, you (TLS client) can set any public_name you want, but the innerSNI can be something else.

Or is that what you mean; since the providers can "ignore" the OuterSNI, they can rely on the InnerSNI to still route traffic?
