From the spec (https://github.com/WICG/compression-dictionary-transport#fin...):

> The existence of a dictionary is effectively a cookie for any requests that match it and should be treated as such:

> * Storage partitioning for dictionary resource metadata should be at least as restrictive as for cookies.

> * Dictionary entries (or at least the metadata) should be cleared any time cookies are cleared.

Given that, I think it offers no more client tracking possibilities than any other existing web tech (cookies, local storage, etc)..

Maybe no more possibilities than regular cookies, but more stealthy for sure. Cookies are (somewhat) easily reviewable by the user through the web developer UI of most browsers; I doubt there will be any browser UI to managing compression dictionary.
