It would be a very welcome addition to get support for JPEG2000 format.
This format offers 16 bit in highly compressed form and in JPX/JPF versions of it allows to save image metadata. Most available imaging software supporting JPG2000 is limiting its implementatin to JP2 - without metadata and only assigning sRGB ICC profile (Infranview, XNView).

I find 99% lossy option suitable for most content. Adobe Photoshop might be the only software which is currently using JPF format fully, with ICC profile and exif. Photoshop CC has a bug that does not allow saving at <100% quality in batch mode. Besides, Photoshop's implementation of JPG2000 is only single threaded. Having Raw Therapee supporting JPF/JPX formats would allow batch-processing of libraries of images in 16 bit highly compressed form.
