Hi,

I am sorry but I don't think we can conclude that. The proponents naturally
are in favor and, given that they will do the work, that is a strong
argument. However, there is often forgotten price to pay when a code moves
from C to C++ that is the reduction of potential contributors. Speaking
only from myself, but knowing I'm not alone, C++ is an awfully complicated
language that is beyond my suffering endurance. Not that it was really
important but there were times I tried to contribute to GDAL but hit the
C++ wall.

I also find the embedded systems argument a valid one but have poor
knowledge on the subject. What I have read here and there is that C++ codes
makes bigger and more resource demanding needs that those made with C.

That said, and as I mentioned in beginning, those that will implement the
new features have ofc the main word.

P.S. Sorry, couldn't resist to point to this provocative reading.
