yes, WKT1_GDAL emulates the behaviour of the GDAL <= 2.4 era. In <br>
particular GDAL <= 2.4 by default didn't include the AXIS[] definitions, <br>
so when importing from such WKT, easting/northing order is assumed.<br>
<br>
Note: GDAL 2.4 supported the EPSGA (A for AXIS) pseudo authority, so <br>
when resolving EPSGA:31467, it outputed a WKT1 with AXIS[]. But I didn't <br>
try to emulate that rather esoteric behaviour in the PROJ 6 rewrite.<br>
<br>
Bottom line: only use WKT1_GDAL for legacy purposes, understanding that <br>
there are a number of potential stumbling points in doing so.<br>
