I know some DFT (*), but very little superconductivity, but I read through Sinéad Griffin's preprint and there was nothing in there which looked weird from a methodological perspective – and the methods (and software) she is using are extremely well-established and well-categorized. (*) it was, like, two decades ago, but I've got a first-author PRB paper so I wouldn't trust me compared to an active researcher but I'm not _entirely_ clueless
