I think that keeping up with DocBook versions is important.

Leaving out the systemitem class simplifies markup.  One nice thing 
about those classes is that they remove ambiguity during editing. 
Without them, it may be difficult to tell from context whether a 
systemitem is a username or a directory name, for example.  Although if 
that is not clear from context, it suggests the text needs improvement.
