Well, basically because they were written in a time when epsg-wkt
was perceived as the best solution (as it does not flip the axis
in the geographic reference systems). epsg-hsql can be used as well,
we just need to setup an system wide hint forcing the referencing
subsystem to return the common axis order (lon/lat) for the
geographic data.

Oh, did you already test and everything worked fine? If so I'm very
much +1 on this option. Otherwise it's just a matter of adding
Hints.putSystemDefault(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER,
Boolean.TRUE);
to the setup and make sure it's run as the very first statement
run.
