Could you useful to know for example how many of the recent CVEs were IPv4 specific, if you have enough token budget to get such data? High level, I don't have must to say beyond what you already know - the code movement may be too painful for backports. There are too many ifdefs (as Stan pointed out). sparse also complains about patch 9.
