Hi  Aaron, and everyone,

It seems like interoperability could be harmed if we release GDAL with a
JP2 driver that writes JPEG 2000 files that the main open source JP2 driver
can't read. Would it make sense to add compatibility to OpenJPEG before the
PR gets merged? Or are we already in a state of inoperability between
