The authors have done a good job at addressing the review comments. There is some differences of opinion but that is to be expected and there is nothing of great seriousness.

I recommend that the paper be published.

Thank you for working hard to address the reviewers' comments.
I concur with the AE - that there are some lingering differences, but that they do not appear to be substantive challenges to the content of the paper and that they are more sylistic that technical. Some others cannot be addressed without more research, but that doesn't mean the work here isn't significant progress. I think the community will make use of these ideas and tools, and may help to address the unresolved issues raised by reviewers in the long term.
