Yes, trailers are built-in and serve the metadata purpose in a fair amount of projects already. There’s also more freedom to be verbose (“Change-For-Downstream-X”) since they are at the very bottom of the commit message. You can even filter out certain trailers with git log. The Conventional Commits people were apparently not aware of this capability when they started (understandable since the tooling is niche). You can see they had some back and forths about trying to get their “footers” in line with trailers and how they had to stumble across misunderstandings about how they work.
