Resources were supposed to be reusable pipelines, but *complete* ones! Later, they were implemented to be usable as pipeline fragments but, IMO, they impose some readability problems in the sitemap. The above aims to correct that.
In fact, if the above is introduced, I would deprecate the use of resources that do not have a complete pipeline.
yes!!! this will be *very* useful. i have had to hack my copy of cocoon to allow resource inheritance in sub-sitemaps just to be able to treat them as "special" serializers just as you mention :)
