The OGC compliant solution is to improve the Simplify WPS process to leverage the pre-generalized hints. If we are going to allow transparent data transformations in WFS why limit ourselfs to simplification? What's stopping us from needing something else, like buffering, or aggregation, bounding box extraction? As I said I'm not saying no, but imho this needs a proposal and a direction, because once we say yes to this other hacks to handle the remaining deficiencies of WFS will surely follow Cheers Andrea -- Ing.
