The not null checks are redundant for sure, but there is no notion of "att
in (list of values)" in OGC filter, so we have nothing else to translate
into (e.g., we have
no way to represent it in our code, we'd have to go beyond the tools that
OGC provided us there, with some risk of becoming non compliant).
What version of GeoServer is that?
