I don't claim security or anything else, but WMS can be debugged without
access to the mapfile, because the units, SRS, etc. are provided as part
of the URL. In CGI, this is all based on information in the mapfile, and
makes debugging hell for users -- it's too easy to muff up the
OpenLayers configuration and not know why you're getting strange
results.
