I'd be interested in pursuing this idea.

The key, for me, would be some form of 'soak test' to prove that what
was built was fit for purpose - that in turn depends on understanding
where these filesystems break, where their 'edges' are - sorry I'm not
being precise here as I'm not competent to judge.  How do you do it now?

I think it's wiki stuff, or hints maybe (if they are not stone dead),
for the moment.  If we get sufficient interest, AND it looks stable, the
editors might put something in the book.  You can't ask them to add new
stuff unless you know how to support it - and who will do the supporting!
