Your patch is a cleaner solution than the +wktext mechanism, which remains
something a bit hacky (although I must admit I had never heard before of that
QSC projection ! and it is probably some niche projection). The advantage of
having it properly recognized is that you can then embed its WKT representation
in a .aux.xml file and all tools using GDAL will be able to deal properly with

But reading again your initial email, I didn't realize that it is not yet
supported in proj, only proposed. So we will wait for it to be committed in PROJ
first before committing its support in GDAL.
