I've went ahead and added support for PointZ like WKT strings in OGR in
https://github.com/OSGeo/gdal/pull/10370, but it would be probably
better that QGIS writes conformant WKT by default (I suspect that fixing
this has the potential of breaking a number of tests though)

Hi,
Both formats are compliant with the WKT specifications.
Are they? I may have missed something in the Simple Features spec, but
looking at https://portal.ogc.org/files/?artifact_id=25355 , I can't
see where it would allow the form {geometryTypeName}Z without a space
between {geometryTypeName} and Z.
For example the BNF at page 56 shows:
<point z tagged text> ::= point z <point z text>
The examples at page 62 also show a space.

A minimal example is below. Executing it will return an exception:
"RuntimeError: OGR Error: Corrupt data"
from osgeo import ogr
qgis_geometyry = QgsGeometry().fromWkt("POINT Z (0 0 0)")
wkt = qgis_geometyry.asWkt() # 'PointZ (0 0 0)'
ogr.CreateGeometryFromWkt(wkt)
