It is not that nobody has built one. It is that the web has no page model, so you cannot even settle what a centimetre is a centimetre of. Taking the recently published editor-ruler as a thread to pull, this post lays out why attaching a ruler is a decision to bring in a document model rather than a UI part, and what follows from that decision.
