Could you explain what these are? They give 404, so I assume they are
more like placeholders and not actually used?

Not sure how you got that list, but probably from git history. I think

Other than that, looks fine to me. Some of the enumerations below look
somewhat hard to parse, but I suspect that it will become second nature
