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.

Best,
