@mikkelfj I'm unsure what you mean in your comment above. The client that receives the packet needs to know the previous Connection ID before it can decrypt it. That means it must be unencrypted.

I don't think we should rely on a model where the client is just expected to figure it out by trying to decrypt the packet for all outstanding Connections. I'm not sure how you would ever support encryption offload efficiently in a model like that.

As far as using a TLS parameter, that goes back to the problem of needing the previous Connection ID before decryption. Since all TLS data is inside the encryption, that won't work.
