not really, unless you regard kde packages in [extra] as duplicates of those in [kde-mod]. jre and jdk is just sun's jdk split into two packages for the sole purpose of having smaller binary packages, but serve no purpose at all if you are building from a pkgbuild.
First of all kde-mod is a good project, but their binaries are not official, and they can duplicate what they want on their repos.
however, if you still see it as problematic, you can well remove it, i'll continue to use it personally anyway..
I can't remove it since I resigned on my TU position, but if I were tu I'd like to discuss about removal (like I am doing) before do it. And if you will be continue using your package then you got the idea about the "Arch's way", and you realized that ABS rocks, and I am glad you got it.
