Thinking further about this, we have to define carefully how this
relates to the "cocoon:" protocol, because in such a case we have _two_
request paths :
- the protocol-level path, accessible using getRequestURI(),
- the sitemap-level path, accessible using getSitemapURI() (different
from the above in the case of a mount or "cocoon:")
We also have to consider that, through getSitemapURI(), the
"getSitemapXxx" names are tied to the current sitemap request (i.e. the
"cocoon:" one).
IMO, the use case is more related to the protocol-level URI : I had the
need for this when building links to images located at the root of the
current sitemap from an abitrarily nested URI (see [1] and search for
"{request:contextPath}/mount/cvssource").
But this is only my view of the problem. Any other use case ?
We also have to consider how to handle the interface change :
- on 2.1, no problem : we're not even alpha ;-)
- on 2.0, there can be some backwards compatibility for people having
implemented their own Request without extending one of the provided
classes. Are there many of them ? I would say no, but if there are,
please stand up !

I have the same use case - and same view :)
...but I am really wondering if there aren't any use cases not only
related to the protocol level. Anyone?

Hm... changing an core interface in 2.0? I guess I am -0 on that...
...maybe we should ask on cocoon-users?
