A handful of suggestions...

I think we might need a doc update based on these changes, but I can do that in a separate PR unless you want to give it a go. If you do, you can do . docs/install-deps in your devshell to install the required packages, then -- and here I'd suggest having no other uncommitted changes -- do make docs. You can then review the changes and undo any that are not pertinent to this change (e.g. lots of timestamps) before committing. It's possible that there won't be any changes worth keeping, but I'd be surprised.

Nice. I'll do the docs update if you don't get to it.

@maddenp-noaa I took a quick look at docs changes and didn't initially find any relevant to the changes to this PR, but I think it's worth another look if you wouldn't mind. I'll leave that for a future PR and merge this one.
