Honestly, I don't really understand the hate that client-side decorations get. I find that they're generally pretty useful and good.
I think a lot of it comes from people who want to 'rice' and theme their desktops but I personally think that dream has sailed. The kind of theming people want on Linux systems is simply not possible without massive amounts of work and downgrades to accessibility, security and usability.
Well, you can disable window controls in gnome and KDE afaik if you want. Then you'll only have the various app-specific buttons that are necessary for functionality.
If you're looking for every app to have a vim-like interface or something, well, that seems a bit unrelated to CSDs.
