I have no problem with kde apps being shipped and updated separatly from KDE (or gnome apps separatly from GNOME)
I think this would be a very good thing.
there is desktop infrastructure, and then there are desktop applications. Most applications can be used on either desktop nowdays, and I personally think that the attitude that you must use KDE to use any KDE apps (or GNOME to use any GNOME apps) is preventing competition between the apps developed for the different desktops.
