It was not hard to do, it's as trivial as drawing 2 buttons and some text. If this is such an issue then take it up with all the app developers. See for yourself how well they respond to accusations of being "antisocial" just for the act of moving some buttons up 30 pixels. This isn't a new thing or a regression on Mac, they always had CSD, even in the pre-OS X days. What is trendy there now is the merging of the toolbar and titlebar, which is different.

And making your window override-redirect, and implementing window motion, resizing, and so on by yourself, since the window manager doesn't do it for you, and dealing with all of the ICCCM and EWMH conventions, and...
All of that was already implemented by the toolkit. The way programs used to do it is by simply calling those 3-4 toolkit functions to move and resize. You can verify this by looking in the code to old versions of Audacious/XMMS/Beep/etc, which still used GTK/GDK to handle those things.
I can't stress this enough: this kind of thing was already supported for quite a long time and app developers were doing it long ago. The only thing GTK3 added was a common look and feel for it. Qt also has that now too.
