This is in fact one of the methods we've been discussing in detail
regarding the need for compatibility with hierarchical systems, and
for a more general means of "grouping" as well.  So far, I think it's
the best option we have.  It would serve its purpose for source trees,
web archives, untarred files, etc.

Indeed it does, and we are thinking about them.  If anyone has good
insight on this idea, please respond to me, or leave some comments in
the discussion pages on the HIG.

The Journal is definitely the next topic on my list to tackle.  It
hasn't been specified simply because we haven't quite reached anything
near a specification, but we're working hard on this problem now.  In
the meantime, I'm liking a lot of the ideas that I see around this
discussion.  Keep it up.
