I understand your point, and I understand that adding many
configuration options might not look pretty to everybody (even to me).
However, the kernel developers want to keep embedded people using recent
versions of the Linux kernel. Unfortunately, the kernel grows release
after release (see [1] for a report, for example), making the kernel
less and less usable in certain constrainted embedded contexts where
older kernels can be used. And people putting Linux in consumer
electronics devices sold several millions times really do care about
system size.

The problem is that this kernel growth is well-spread over all the code.
So yes, it's 6k here, 10k here, 7k there, but once added, it starts to
be significant.

That said, I'm well opened to suggestions on how to better fix the
kernel in that respect.

Thanks,

Thomas
