I can dig out specific posts if you really want me to. But Gez is quite 
correct - the notion of "backwards compatibility" has from time to time 
received considerable mention on the gimp developers list.

Gez hasn't posted any false information. His choice of comparing 
attention to themes with attention to the big picture regarding the 
direction GIMP has taken with respect to the needs of people using high 
end workflows was a bit unfortunate (the new themes are very nice and 
also the result of a lot of work from people who don't normally write 
code for GIMP). But I 100% understand and share his frustration.

1. Get rid of the babl flip code and attendant linear vs "gamma" 
precision code. Rip it completely out of babl, GEGL, and GIMP. I wrote a 
patch for this back in 2014, and I'd be happy to write a new patch for 
today's code base.

2. Apply my patches for allowing to edit in any well-behaved user-chosen 
RGB working space.

A start on the above two items is available from my github clones of 
babl/GEGL/GIMP: https://github.com/ellelstone

The new menu items shouldn't do or say anything. They should be removed. 
If a GIMP user doesn't want to deal with color management, they already 
have the option to only edit sRGB images.

Best,
