What problem are you trying to solve?

The Compression Dictionary Transport spec defines a link relation for loading compression dictionaries. The HTML implementation of the link relation should be spec'd.

What solutions exist today?

None.

How would you solve it?

Define the compression-dictionary link relation behavior to mirror the behavior of a prefetch except for passing "compression-dictionary" through to fetch as the initiator and defaulting crossorigin to "anonymous" (instead of No-cors).

Anything else?
