Yup, that's what I was discussing in my original mail as long term
approaches:
- have the filter be defined at the layer level (since we already have
the "definition query" support in the code that is not exposed in the
GUI)
- have some vendor option in the SLD at the Style, FeatureTypeStyle or
Rule level to allow specifying whether a filter is actually filtering
- add support for classification functions so that whatever is in the
rule filter is... actually a filter you want to pass down
