So far as I know, it would only matter if there was some giant security fault that people could exploit. Who cares if they know you're using Struts if they can't exploit it. You could always change the action
servlet filter to pretend it's using something more primitive like *.html or *.cgi, or something arbitrary like *.hireme.
I don't see many people explcitly changing it though -- the traditinal "do" seems adequate for most.
