11 * [`ChannelMonitor`] should be made aware of.
13 * Because this represents only a small number of updates to the underlying state, it is generally
14 * much smaller than a full [`ChannelMonitor`]. However, for large single commitment transaction
15 * updates (e.g. ones during which there are hundreds of HTLCs pending on the commitment
16 * transaction), a single update may reach upwards of 1 MiB in serialized size.
