I too think we should call it 1.5.0 and issue a 2.0 once and if any changes
roll out of the OGC efforts. Specifically, I think that your proposal for
formalization of a WKT key is something we would find very useful in lidar
land. https://github.com/opengeospatial/geotiff/issues/56

Did GTIFDeaccessCSV and SetCSVFilenameHook get removed or no-op'd? I
suppose I'd vote for the latter. Removing them is going to sprinkle
#defines in code for not much gain, right?
