Hmm yes I see your point.

dzhandle does this, or something like this.  It creates a directory
structure in $INSTANCE/Products that mirrors /usr/share/zope/Products
and then symlinks each individual file in each directory to it's
counterpart.  For example:

It would seem to me to be far simpler to just symlink the two Products
directories, but no doubt there's a good reason why they don't do
that.
