This is a very confusing read, so let me see if I understand what you just said:
We don't need %NAME% and %VERSION% in the database 'desc' files
because we can parse this from the directory name?
If so, I think this falls in the realm of "premature optimization" -
there's no reason to do that at all, and you're assuming the DB files
will always follow the same pathing structure.
