Thanks, I'm hesitating a little on the doc one, as we have no other doc packages listed... but all the other ones should be there and updated now.

Thanks Daniel, looks good!
Also nobody ever mentions the ...-debuginfo packages that are built alongside all utility and library packages.
Splitting docs into a separate package, especially from ...-devel and gtk packages, appears to be a legacy of RedHat heritage; if maintainers even bothered to package the docs ;^p
I know admins always skip doc, man, and dev tool packages on prod servers, to avoid any possibility of doing any kind of dev activity, nothing like any build or interactive work.
On commercial Unix dev servers, minimal docs and man were available, and hogs like Emacs and GNU packages were prohibited.
Linux and RHEL dented that to some degree, but packages available on dev servers are still less than any normal desktop builds, due to network threats, package security validation requirements, and minimal maintenance windows allowed.
