Not pointless. If people don't read package changelogs/releasenotes,
then it is highly probable they miss new features in the packages.

A ChangeLog in the root of the source dir. is almost mandatory in autotools
distributions. Despite the existence of a somewhat standard format for ChangeLogs,
it is not enforced leaving the need to parse all the crap they through at us.

"There is an optional <changelog> tag in metadata.xml."

That really looks like a better solution and it is something I might
start putting on the packages I maintain.
