The question is what the cost of that duplication is.
If someone has to *maintain* duplicate files, that's
a problem.

If the duplicate files are automatically generated
from a single master, so that only a single file has
to be humanly maintained, that's not much of a problem.

Since the configuration files are straightforward
data structures, how hard would it be to have a module
that generates all the variants?
