yes, there was indeed a discrepancy between the documented behavior of 
the PROJ C API and what the PROJ C++ API offered to fulfill it. That 
should be solved by https://github.com/OSGeo/PROJ/pull/4108

However as noted in the updated documentation, the distinction between 
warnings and errors is probably not that much relevant, and the mapping 
to the OSRValidate() API that dates backs to well before the complete 
revanp done in PROJ 6+GDAL 3 is even more arbitrary. The bottom line is 
that if OSRValidate() returns a non-OGRERR_NONE code, there's something 
that is non nominal, and human expertise is required to assess if it can 
be ignored or not.
