If I open the details expander of a package, all I see are the new and old version numbers of the package, presented in a cryptic way (architecture included, etc). If that is all the details we have about a package, I think its not worth displaying it.
The plan (hope?) is that we get to where the update information is available via the metadata and so then we can show something better. Until that happens, there's not much more we can show. We just have the package versions, releases, etc (and arch is somewhat relevant for, eg, x86_64).
