The problem is, while there’s divergence in some areas, there’s still shared code in many (most?), and it currently requires human judgement to determine if passes form both count as two independent implementations or not.

If someone wants to generate a map (keyed by spec section) where there’s divergence (or the converse would be better, since that set isn’t getting bigger), I’d be happy to have the test harness automatically differentiate the results.

For the record, each result is keyed to the full UA string that generated it, so we can always go back and re-assign results to different products.

I think we should keep it for a while longer. As it provides useful information to the people working on the spec or the tests.

No reason to remove old passing implementations… I’ll take passes from Lynx if it helps get a spec to CR.
