I disagree for several reasons.

First is that if the load on the network is high enough, conversations
can hide in the noise. This is helped by dummy message generation
either by clients or servers (preferably clients to protect against
attackers that can monitor every node).

Second is that this protocol is not necessarily one-to-one. It
naturally supports one-to-many, many-to-one, and many-to-many
messages. As these are not distinguished at the message layer, but
rather at the application layer, it would take some more sophisticated
analysis to determine the nature of the conversation.

Third is that prefix selection logic is entirely up to the client.
They can choose prefixes that vary with an encrypted pattern, or some
variant of that idea, to obfuscate where they are sending their
messages.
