The appropriate mailing list for this kind of question is debian-kde.
By the way, you are wrong:
kdevplatform1-libs | 0.9.92-1 | unstable | alpha, amd64, armel,
hppa, i386, ia64, s390, sparc
kdevelop | 4:3.9.92-1 | experimental | source, amd64, armel, i386, ia64
kdevelop4 should be available on i386.
