At the risk of overengineering, perhaps the easiest way to deal with
format bikeshedding is just to define an enumeration of formats just
like the enumeration of licenses. That way machine-readable formats are
annotated by which machine should read them, but crotchety developers
don't have to change their changelogging preferences. After that's in
place, then we can worry about the social pressure to get the community
to agree on a smaller set of formats (just like has happened with licenses).
