Whether or not to use it may be a political rather than a technical
motivation. But the reason I acked this patch is not because removing
it aligns with my political conviction regarding Speck, but simply
because its contributor, primary intended user and therefore de facto
maintainer stated publicly that it no longer had any intention to use
it going forward.
