Cloudflare and similar services seem well positioned to take advantage of this.

Analyze the most common responses of a website on their platform, build an efficient dictionary from that data, and then automatically inject a link to that site-specific dictionary so future responses are optimally compressed and save on bandwidth. All transparent to the customers and end users.

This seems like a lot of added complexity for limited gain. Are there cases where gzip and br at their highest compression levels aren’t good enough?

It seems very odd to use a colon as starting and ending delimiter when the header name is already using a colon. Wouldn’t a comma or semicolon work better?

It’s encoded using the spec that binary data in headers should be enclosed by colons: https://www.rfc-editor.org/rfc/rfc8941.html#name-byte-sequen...

Oh, thanks, it looked like a string such as a hash or base64 encoded data, not binary. Don’t think I have ever seen a use case for binary data like this in a header before.

That `Link:` header broke my brain for a moment.
