Since this capability of working around issues in certain levels of
Apache requires both the server name and version to be advertised,
that is an argument against something you've been able to do since
Apache 1.3.14 (hide the version).  Colm had another argument in that
category.  So we could list some reasons to avoid using the existing
capability to hide the server version:

* make it easy to audit your web server installations for out of date versions
* allow other software, such as proxy servers, to work around problems
in your level of Apache
