Design/Reminder: setupChannel calls session.activate (channel) until late, shouldn't it be done immediately?

Or should channels always be activated implicitly to begin with?

Currently we create channels, but they need to be manually added to the list of pingable channels, but I wonder if we should always activate them instead - that would have avoided this code:

        // Now, make sure we process any data that might have been queued while we were setting up before the channel activation.
        let _ = await channel.ping()

And perhaps this is the source of other blocking operations, as we are calling things on the channel, but have no way of feeding them.
