      For single-collection change streams, high water mark tokens received from shards on which the collection does not exist will always omit the UUID. While these tokens function perfectly well for merging purposes, PBRTs returned to the client without the appropriate UUID cannot be used to resume the stream, since we cannot accurately determine the collection's default collation.
