That's a good question! I think a good way to figure that out is to publish a paper about what they did, how it solved their non-trivial problem, and then invite others to try to use their tool and techniques to solve their problem. In other words, you're asking a question that criticizes the mechanism that would answer that question. It's a legitimate question, but a poor reason to disregard what they did.
