surely, and sadly most of the stuff was diesgned with no awareness of
that fact - you can't supress the version in ssh because it#s part of
the proctol, the sme for mysql and httpd even refuses pacthes where you
simply can remove the sevrer header because no client needs to know what
type of webserver there is running at all

in other world: most developers don't care otherwise this would not
exist or at least not leak exact versions
