Specifically, I think that guidance for implementers about use of fragments is useful, especially in documenting current behavior on the network and the justifications for it. However, we're starting to get a lot of overlap between the drafts dealing with fragmentation, whether it should be deprecated, whether we should simply provide a caveat implementer statement on using fragments but leave the standard alone, etc. It makes matters worse when one considers fragmented packets together with large headers, since at least some of the technical considerations overlap.
Imho this is the first of these documents in recent times. As an author
