Yes, I think you're right. The ROOTFS_OVERLAY feature was added to help
people that are in the simple case of a rootfs overlay stored in
board/<something>/<foobar>/, and make the possibility of using a rootfs
overlay more practical to use for newcomers.

However, for more complicated/specific cases, using the post-build
script remains the right option.
