Ship it!


Only some docu is missing: @since 5.0 in the new namespace (or its methods, rather), and porting instructions in KDE5PORTING.html

Most existing users will be unaffected and gain the ability to stop linking KIO if they don't need it. New users won't be confused over why something as canonical-sounding as KAuthorized is in KIO.

However, this would mean duplication and a lot of porting churn away from deprecated API, and in the meantime not address the linking issue.
