Blueprint doesn't run $this->getFooterLinks or offer a replacement of it that provides any of the copyright/privacy/about/disclaimers/project links.
See the footer of e.g. https://www.mediawiki.org/wiki/Manual:Skinning?useskin=qqx
This makes it tough to address T317: "Terms of Use" must be prominently featured in the Developer Hub. Do we envision a footer in Blueprint, or something better?
