More tightly, I am not sure. However...

... these tools are intended to be used by post-image scripts, so
boards could provide both a genimage layout and a post-image script.

I am not sure we would want to integrate that into buildroot itself.
I am afraid doing so would complexify the infrastructure.

Also, the fakeroot jail is restricted to the filesystem image generation,
and post-image (and post-build) scripts are *not* run in the fakeroot,
although it is trivial to re-enter a new fakeroot from inside such a
post-{build,image} script, a-la:

    #!/bin/sh
    if [ $(id -u) -ne 0 ]; then
        exec fakeroot "${0}" "${@}"
    fi
