In that case, you already need to install the kernel in order to test
it, so you might as well install the headers along with it.

Also, you're not normally touching multiple headers at a time, but rather
add a feature in one file, so it's not hard to add it to both copies of
that file. This may seem like an unnecessary step, but using the kernel
headers without installing them first can cause any number of problems
that we don't want anyone to have to deal with.
