> One thing that would be unsafe would be to ref the connection but I made sure the static functions that are use uniqueID don't do that.

Sending of the message *ALSO* creates a ref to the connection, so this is wrong too.

bool Connection::sendMessage(UniqueRef<Encoder>&& encoder, OptionSet<SendOption> sendOptions, std::optional<Thread::QOS> qos)
{
...
    auto sendOutgoingMessages = [protectedThis = Ref { *this }]() mutable {
        protectedThis->sendOutgoingMessages();
    };
...
}
