Concerns regarding large Link headers with Link Hints

[RubenVerborgh]

Following Appendix A of https://tools.ietf.org/html/draft-nottingham-link-hint-02, the Link Hint JSON structure can be serialized in a Link header.

However, this seems to result in rather large Link headers, and it seems a strange precedent to stuff JSON in headers.

What is the design rationale behind this?
Aren't we better off just linking to a Link Hints document (which could be cached and, with HTTP/2, be pushed)?

Actually, the approach to provide a set of links in a dedicated document, as described in the "linkset" I-D, could be used for that purpose, see https://tools.ietf.org/html/draft-wilde-linkset-06.
