It's still interesting to look at, but more as a curiosity. Maybe some of those ideas might come in handy someday. But I wouldn't start learning these as super successful design pattern and start forcing them onto your next project.
Back story:
What might be useful is an approach of live collections that keep evolving / added to. Maybe some sort of extension of the Journal of Open Source Software [1] where authors focus purely on architectural aspects.
Having a classification (by technology, functionality etc.) would also make it easier to make the most out of this wonderful collection.
I wish there would be more books in this series.
