The lock down to a specific version of the kernel and a specific version
of the kernel headers is intentional. These are here to guarantee that
the defconfig will always produce the same result, regardless of
whether Buildroot updates the default kernel / kernel headers version.

So this should be kept (possibly updating to a new kernel headers
version of course, but we should keep a kernel headers version here).

Same thing here. No problem with bumping from 3.8.x to 3.12.x or
something like that, if you've tested 3.12.x, but an explicit version
selection must be kept.
