Did you actually look at the screenshots? KDE did not remove separation between elements. However it is now achieved by drawing a single line between two elements, instead of framing every single thing which is extremely ugly.
I also find Kate '6' to be much more pleasant to use, because this separator is still clear enough, but actually uses marginally fewer pixels which is nice on my low-resolution laptop.
