Hi Jody,
Yeah, I know. Axis order has been quite messed up, especially for 4326.
However note that I'm not using 4326 but 4258. There are no special
considerations (at least to my knowledge) that need to take place here, and
as such, I don't believe there is any reason for GeoServer to use a version
of the CRS where the axis order is forced to east-north.
