[Gimp-developer] The darktable plug-in isn't using the user-specified output ICC profile

It would be nice if the darktable plug-in were modified to allow users to choose their preferred output space.

But currently darktable does seem to force output to be in the darktable version of linear gamma Rec709 (which isn't equivalent to GIMP's internal linear gamma sRGB color space - https://mail.gnome.org/archives/gimp-developer-list/2016-April/msg00116.html -, but hopefully this can be changed).

Right now GIMP is an "sRGB only" image editor. But this situation surely won't last forever. Having a raw processing plug-in that only allows to export in one color space (especially a color space that doesn't match the GIMP built-in sRGB color space) seems to be a step in the wrong direction.

Also, only some GIMP operations are "sRGB only". Many operations work just fine using any RGB working space chromaticities.

Presumably at least some GIMP users will sometimes want to edit their interpolated raw files in RGB working spaces other than sRGB, and GIMP does allow this to happen. So it doesn't make sense that the darktable plug-in prevents users from exporting the image in the user's chosen RGB working space.
