Indeed. The only way such questions are useful, is as a starting point, maybe they make the candidate more comfortable (less nervous), and they also ensure that you're not asking something the candidate is completely unfamiliar with.
But in any case, any such "experience" or generally "subjective" question must be accompanied by further detail-oriented questions - why did you do this and not that, tradeoffs of different solutions, "how does this framework/library work underneath", questions about understanding performance/security etc characteristics and why, etc.
