Maybe, but I think people often check out and compile kernel sources only.
E.g. users of the stable releases.

Making a feature branch of only the kernel is also easier if the kernel is
contained in one directory.

No, because you do not need to check them out to compile a kernel.

I already mentioned users of stable binary releases. Another use case is
to check-out the whole tree and build the tools, but do it only once and
check-out the kernel source multiple times to be able to work on multiple
features. Having more directories is quite inconvenient in this case.
