I can't say I'm surprised at that. Sun hardware tends to be rather more
hierarchical than is the norm in, for example, the PC space. This
particular document came into being during the CHRP era, when IBM and
Apple were trying to glue a Macintosh legacy I/O system onto the side of
a PC legacy I/O system. The result was not pretty.
Sun had at least the semblance of a coherent architectural design and
review process.
