there's slideware on this from 4 years ago: https://www.ietf.org/proceedings/interim-2021-core-05/slides/slides-interim-2021-core-05-sessa-core-option-for-well-known-resources-00.pdf IMO the hard parts are: 1. Not giving in to the feature creep (p3) 2. Know when to use it (try, assume any Bad Option is ours unless problem-details tells us otherwise, retry with spelled out path?) And there's a caveat that when combined with query parameters, the server needs to go over the options once more (but that's mainly relevant for .well-known/core I think).
