And, if there are other sources I've missed, either for sale or buried in a forum discussion or blog or something.

Thanks!

The notable gap in your list is actually High Tech, which has a replacement, usually seen as superior, to the Basic Set Hiking rules.

It's possible one of the sources you have replicates this, but I don't think so.
