You know, I think you've about covered the boilerplate work.  Apart from
that, well it took me a millisecond to work out what the point of
config_{group,item}s was; I went in kinda expecting to see one struct
for directories and one for attributes.  In fact I still not sure I can
explain the need for config_items separate from config_groups.  Little
help?  :-)
