*very* little software should need a seperate kernel header package. You
only need them for compiling device drivers that need the exact kernel headers
your kernel was built with.

Linus and Debian disagree with you. Unless you are rebuilding your libc
with each kernel upgrade (and all other libraries, really), you should not
be changing kernel headers on applications. This can cause subtle breakage
that you won't be able to debug. The size of structures can change or be
reorganized, and the lib will see one view of the structure, and libc will
see another, ending up in crashes or weird behaviour.
Basically, you don't really even need the kernel-headers packages installed
unless you are compiling some sort of specialized driver, and have upgraded
your kernel.
