Andrea,
You are too positive in saying "(there are a few projected ones that flip
anyways, but they are
a small minority)". Majority of the compulsory INSPIRE systems are
Northing-Easting (ETRS89 / LAEA Europe) like
http://epsg-registry.org/report.htm?type=selection&entity=urn:ogc:def:crs:EPSG::3035&reportDetail=short&style=urn:uuid:report-style:default-with-urn&style_name=OGP%20Default%20With%20Urn&title=EPSG:3035

Aihe: Re: [Geoserver-users] WMS GetMap 1.1.1 versus 1.3, CRS instead of SRS

The major differences between versions 1.1.1 and 1.3.0 are:
In 1.1.1 geographic coordinate systems specified with the EPSG namespace are
defined to have an axis ordering of longitude/latitude. In 1.3.0 the ordering
is latitude/longitude. See Axis Ordering below for more details.
In the GetMap operation the srs parameter from 1.1.1 is now crs in 1.3.0.
Although GeoServer supports both regardless of version.

EPSG:31370 is defined as:

It is a projected SRS, so its axis do not flip (there are a few projected ones
that flip anyways, but they are
a small minority).
All the geographic ones (e.g., EPSG:4326) suffer from axis flip instead
Cheers
