Yes, that's reasonable.

Need to say, we have a big trouble with kernel development due to
/usr/include/{asm{,-generic},linux} directories instead of symlinks
pointing to ../src/linux/include/{asm{,-generic},linux}. For myself,
I use the following in my kernel.spec:

%define _srcdir %_prefix/src
%define _linuxdir %_srcdir/linux

%post headers
test -d %_linuxdir \
|| ln -s linux-%version-%release-headers %_linuxdir
test -d %_includedir/{linux,asm,asm-generic} \
|| ln -s ../src/linux/include/{linux,asm,asm-generic} %_includedir/

That means, these symlinks are created only if there are no ones.
Obviously, if I need to switch to another kernel, I simply modify
the /usr/src/linux symlink to point to the needed directory - that
allows experimenting with newer kernels, which I need on a regular
basis for supporting modern hardware.

I think we should provide both, in separate packages (kernel-doc and

IIRC, we don't use perf at all...

They could be split to separate packages.

My suggestion:

kernel-source (full /usr/src/linux-%version-%release directory),
kernel-firmware (for code built as modules),
kernel-modules-xxx (for xxx support),
kernel-modules-yyy (for yyy support),
