I do occasionally use "srgb," though.

* Not really frequent.
"gamma" setting for input images is something I dearly wished for in
POV-Ray 3.6, but the new image_map default in POV-Ray 3.7 ironically
obviates the need! (I searched all my scene files, and not once have I
ever used it.) It still seems like a good idea to have this feature
available, though.
