No, they really don't. I just listed the files in a kernel-devel rpm and the
only .c files are in the scripts directory. It's pretty hard to compile the
kernel without any source.

The rpm installs to /usr/src/kernels/$VERSION
I suggest you browse that directory again and note the lack of .c files.

What do you think people run?

No, you were asking off-topic questions. Just because you were bastardizing
source code from CentOS doesn't mean we need to support it. Why don't you go
ask in #redhat and see how it goes over. Better yet, open a bugzilla entry.

See above. Do an rpm -qpl kernel-devel-foo.rpm. Look for .c files.

CentOS merely takes what RH gives us. If you are so convinced the problem
lies there, take it up with them.
