Also:
couldn't each fieldset have a list of jsonPath elements (similar to what is done in
draft-ietf-regext-rdap-sorting-and-paging)
to properly list the fields concerned?

TBH, I am not sure to understand:
- why there are multiple links elements (the example given shows only one, what would be other ones?)
- why value there is different from href (and hence why value is needed at all),
why is the current fieldSet the "context URI" of any other fieldset used for same query?

RFC8288 defines the context URI to be, for HTML serialization:
"The context of the
   link is the URI associated with the entire HTML document. "

There is no real explanation of the context for RDAP, but based on that maybe
it should be a link to the same query with fieldSet "full"?
