I did a quick skim over this and this looks good to me. I'll rebase this PR to go to b4b-dev, which should be fine without any trouble. Sometimes you have to rebase the branch when that's done, but I don't expect that now.

The one thing noticeably missing is an updated parameter file with the parameters moved to it.

Adding next to talk about who will shepherd this in.
