Should be fixed, see the other thread. Once you confirmed that the profiles are 
fine now we will release darktable 2.0.4.

The reason I chose linear sRGB is that

1) we are exporting to EXR as the intermediate file, so we need a linear profile
2) GIMP seems to work best with sRGB images so far, so I used the linear 
version of that.

I agree that it would be nice to have some choice there. Would default export 
to linear Rec2020 be better? Still hard coded, but a wider gamut. It seems 
GIMP asks about converting the colors anyway, so for people that want to work 
in sRGB that's just one click away.

Having a way to actually change the profile from darktable on the fly would 
require some changed to darktable that I don't want to do right now (pending 
release, breaking things, you know the drill). Eventually I will think about 
ways to fix that though.
