+/// ChannelManager)>::read(reader, args).
+/// This may result in closing some Channels if the ChannelMonitor is newer than the stored
+/// ChannelManager state to ensure no loss of funds. Thus, transactions may be broadcasted.

+/// ChannelMonitor::get_monitored_outpoints and ChannelMonitor::get_funding_txo().
+/// 4) Reconnect blocks on your ChannelMonitors.
+/// 5) Move the ChannelMonitors into your local ManyChannelMonitor.
+/// 6) Disconnect/connect blocks on the ChannelManager.
+/// 7) Register the new ChannelManager with your ChainWatchInterface (this does not happen
+/// automatically as it does in ChannelManager::new()).
