OK let me try to summarize my thoughts in a bullet list fashion :-)
- C++ as mostly for internal use for new code to be added, related to CRS 
modelling and WKT managment
- Part of that C++ code as possibly externally accessible
- Part of that C++ externally accessible API might also be exposed through new 
- existing proj C API still available through the plans exposed in the past.

The first 3 bullets are quite similar to how GDAL handles things.
