Yeah, I don't think interpret-trailers is currently a useful tool for looking at an extra config key like that. I'd expect it would need to be extended, or a new tool added, or perhaps existing tools would need to learn more about how trailers work (e.g., it would be nice if git-log could do matching or even print them via %(trailer:reported-by) placeholders or something). I think there's a lot of potential work in that area. Of course git-contacts (or send-email) _can_ just look look at all of the trailer.*.autocc config and try to match those manually. But the point of having trailer config, I think, is that we should stop doing ad-hoc parsing and have a tool for manipulating and querying trailers. If interpret-trailers isn't up to the task yet, I'd rather see work go there. But that (manual parsing) is basically how the current cc and s-o-b trailers implemented inside of git-send-email, so I don't think it would be the end of the world as a quick hack that could later be expanded to use the trailer infrastructure. -Peff
