Changes to the sitemap don't require recompiling and restarting tomcat.
If you need to do it, there is something plainly wrong with your Cocoon; I
can't imagine how you managed to keep using cocoon given this :-O

Anyway, the main reason is architectural.

Cocoon was made with a sitemap because this makes the flow control and the
component declaration in a central place; the whole site is much easier to
administer and the components are easier to reuse.

If your Action redirects to a specific url, it's difficult to reuse it in
other sitemaps.
