I also have fond memories of !SquashFS but the problem is that some
people want named streams on _directories_, which means that these
directories need to be both directories-of-files and directories-of-streams.
That's harder to disambiguate.

I think providing two new tools (or variants on existing tools) --
streamcat and streamls should be enough to enable operating on named
streams from the command line.  If other tools want to provide the ability
to operate on named streams directly, that would be up to that tool.
