The first thing that the RSSAC wanted to know was how the various implementations responded to the priming query.
Do you mean how the various resolver implementations form a priming query, or how they interpret the response? The implementations that respond to a priming query are surely just those that are in use in {A...M}-Root.
But that is very much a surface question. I think the broader question included "what might we learn from looking at the various implementations, how they differ and how they are the same?" For example, if a bug or incompatibility were to surface, we might want to advise the developers or the operators that deploy the code.
Is there a list of implementations already in existence, perhaps sorted by some measure of relevance (traffic, end-user population, etc)? If so, has there been any effort to compare the list (or the sorting) with the analogues constructed using traffic received at TLD servers? It seems like the difference, if there is any, might indicate a subset of root-specific concerns. I appreciate if I had been paying attention recently I might already know the answers to these questions, so sorry about that :-) Joe
