The issue fundamentally is that most people do not use this kind of knowledge on a daily basis - even those of us doing low level work, and when it is needed, it is a mere web search away - or if necessary I can reach for Knuth.

I think you misunderstand my notion of a "google gotcha" - I'm not proposing that interviews do not into rigorous technical detail. I'm proposing that interviews that test knowledge of easily-looked-up trivia rather than an understanding of engineering pragmatism and trade-offs are fundamentally flawed and yield markedly worse results than those that do not _regardless_ of company.
