Yes, I meant the proposed approach with a regulaltory domain per countrycode won't work with those fancy ones.

That sounds like a doable way to start with the per countrycode domain and traverse to the optional refinement values on demand.

BTW, would this render the countrycode to CTL mappings in regd_common.h redundant, or do DFS and CTL domains differ?

To start with support for unified DFS domain CCs, was there ever some v2 for the related patch set you posted?
