Yeah, your point about needing to own the entire stack in this case makes perfect sense, and to be honest, I didn't qualify what I said well at all at the time. When I left the interview I had that sense of "damn, why did I say something so strange with no explanation of where I'd seen this or argument against it". There could have been a conversation about it, but my response just made the interviewer tick the 'no' box.
