Also how does this relate to #1376?

As Anne has pointed out there's an existing explainer. This should redirect from the old explainer and the old one should be moved, deleted or otherwise handled so we don't have two show up. Feel free to link back to the old one from the new one

Let's keep and link to it, don't delete it but keep the same URL so that anyone that linked to the prior one it still functions as expected. There's valid research in the prior one that we should retain

@annevk @gregwhitworth @lukewarlow The new explainer links to the old one in the "Alternative proposal" section and in "Alternatives Considered." Please let me know if this is insufficient in any way. Also, the old explainer will stay at its current URL, no changes to it in this PR. Thanks!

Approving but one nit, you have dual counting occurring. Thanks for the work on this
