Okay, I'll argue this now: I for one would like to keep more @rel values than PaceFieldingLinks retains. From PaceLinkDelicious and PaceLinkConstruct:
about: The URI in the href attribute points to a resource that is the topic of an entry. (sort of like "the primary 'related' link")
start, next, prev: moving the "sliding window" along the feed--necessary if one wants to "catch up" on missed entries.
comment: I assume primarily to point to a comments feed for the entry
There are others to which I wouldn't object, but which I myself would find less useful, so won't mention here.
