You could certainly code each Action as a Servlet but it would take more work. You've mentioned changing the Servlet spec several times and seem to be under the impression that it's easy to do. Open source software has certain advantages over standards because it is easier to try new things. It's *much* easier to change Struts than to change any Java specification including Servlets. But you should notice the huge influence OSS and Struts in particular has had over the standard technologies. Struts directly contributed to JSF and JSTL with ideas and pressure to make the standards better than the Struts version. IMO, that's a much more effective way of changing things for the better.
