We need to have a detailed analysis about what changes have been made to the spec in the last two years and how do we include them here. We might need a report on current attributes of the spec and what core is missing.

As far as I can see, now that we have separated the repos, all changes to the spec can be done here without having any changes in hydrus itself. We expose interfaces for hydrus to use core to understand the API, but all spec related changes will be made here from now on.
