Okay, I did it another way anyway. If it's useless, do you suggest that
the ttl parameter in the Transport header should be removed altogether?
Or the issue will be moot if we always force the TTL to either 1 or 255?

I'm afraid that users who purposefully set the TTL to a given value to
control the scope of the stream will miss the option, what would you
tell them?
