Hi Keith, This patch is also sitting in the patchwork for a long time without a decision. I am not against this script explicitly, but we already has a solution what this script does and I don't see the motivation to replace it. Perhaps we may need it when switched to meson, I don't know if we have a solution in meson, cc'ed Luca for comment. Unless there is a demand/need for it, I am for updating it as rejected.
