I find the information in the commit message useful, and it tells me who were explicitly included in the discussion. For example when fixing a regression I'd like to Cc everyone who was Cc'd in the regressing commit. The drm subsystem maintainer tool actually has a helper for doing just that. 'dim fixes <sha1>' digs up all the relevant info. The Cc's on the mailing list archive are harder to dig up, and do not accurately reflect the same information. A lot of patches get sent with more Cc's in the mail message than in the commit message.
