Yes, but the Buildroot infrastructure makes it a lot easier to
integrate the Xenomai userspace libraries separately from the
kernel-side patching integration. Moreover, as detailed in the
documentation, there are people who do not use Buildroot to build their
kernel, but only to build their root filesystem.

Or maybe I missed your point ?
