Lots of reasons, eg. confuse newbies ;)

I suspect it is due to user-space applications.

The kernel needs to be built with the compiler that was around
at the time the kernel was released, eg. a 3.x generation compiler
with a 2.4 generation kernel. If you try and use a new compiler,
eg. 4.x, to build an old kernel (2.4), you'll often find that the
code won't build at all. Conversely, 2.6 kernels also require a
fairly recent compiler to build (I vaguely recall a binutils
update that is required). Basically, the compiler has just gotten
better at detecting bugs or illegal statements and will no longer
accept them.

User-space code on the other hand can generally be compiled
with any generation of compiler, assuming libraries and other
dependencies etc are resolved.

Cheers,
Dave
