I can see value in a more explicit facility for redirecting to an 
existing sitemap match as opposed to a resource.  However, if this is 
the case, then I presume that the passed parameters would be treated as 
http request parameters and not variables in the environment map.

For reasons of accessibility there are situations when it would be 
extremely valuable to output the contents of another web page in 
response to request failure or other detectable condition without using 
a 'real redirect' (status code 302).  Real redirects are considered a 
'no no' on accessible sites but producing the resulting pages as 
resources instead of site matches seems clumsy and unrepresentative of 
the intention of the code.

I believe that this facility is already available in the form (but I 
haven't tried it!):

	<map:redirect-to uri="cocoon://path?param1=value1&amp;param2=value2" />

But as Konstantine says, this is not very intuitive and I would be +1 
for:

	<map:forward path="path">
		<map:parameter name="param1" value="value1" />
		<map:parameter name="param2" value="value2" />
	</map:forward>
