doc shepherd: re-review and write-up status

[npdoty]

Agreed at IETF 114 that shepherd (that's me) would re-review to make sure my comments were addressed and any clarifications necessary on the per-issue organization of the document.

@nllz or @claucece, can you add me to this project and assign this issue to me?

[claucece]

Added you (with some read access), and assigned now ;)
