> I would think that if it’s much easier to agree on “here’s what I saw”, then it would work better if the first draft includes the problem statement, and then later drafts flesh out “here’s what to do about it”.  Even in practice, simply agreeing on the nature of the problem, is of limited value without the knowledge of solutions, or even the knowledge that a solution may not exist yet.  Even if there are multiple solutions to a problem, it is always important to state the problem that each solution is designed to solve when presenting any solution.

Indeed. As an author of the ‘what I saw’ it seems appropriate to document an issue that others can discuss and decide what action(s) to take.  

So separation of authorship is one thing.

Another is that there might be multiple ‘here’s what to do about it’ documents, as there have been with other operational problem statements. There might be Informational or BCP documents in v6ops suggesting mitigation methods, and/or there might be protocol changes through 6man.
