I prefer the analogy of asking if Einstein theory of general relativity was correct before the technology was available to prove it correct ;)
Two serious points though: I didn't say "untraceable" I said 'a lot harder to decide why'. Secondly - if you start with the premise that hints are ignorable, this means you may give up much too soon when trying to use a hint and do something nasty like turning a SQL statement into a great long screed of procedural code. Not that I approve of hints, mind you - but sometimes hinting is the least-worst short-term solution.
