Even, I'm +0 on this change.
On the one hand, I *like* the fact that the dlopen() approach means that adding libproj.so after the fact means that GDAL starts supporting coordinate system conversion without a rebuild. On the other hand, it isn't clear why we do this only for libproj. I have some appreciation for Ivan's stated concerns with regard to regression, but I don't think that should hold back cleanup in major new versions.
