Consider it if
People who want one reusable one-litre container and find a visible time marker useful as a non-prescriptive reminder.
Skip it if
People who already own a suitable bottle, glass or cup, anyone who dislikes hand washing or a large container, and readers who need individual fluid guidance rather than generic markings.
