Im certainly not against the idea of useful tool..however - Its not like a test suite that a bunch of ppl create (and the test tool itself can be buggy of course) will solve all issues. A lot of incompatibilities are there for other reasons.
The world will never run out of whining ppl, thats for sure. Im simply saying that what will make the end user satisfied is how well the product works in 99% of everyday usage cases not so much what value a test tool returns. But if you can use that tool to more quickly arrive there, fine.
