What it was doing was casting the input buffer to another TRC, basically pretending the data was what it was not. In particular, it was casting linear input buffers to non-linear and all other TRCs to linear. As was noted in #1958, this was in fact a useful trick, yet it's still a trick. Basically when it's needed, it's either: 1. because the operation implementation does not work in the technically correct space. Then the operation code should be fixed; 2. or because several work TRC are valid, then an option should be proposed by the operation; 3. or for artistic reasons, which people are free to implement as plug-ins or third-party filters, but it should not be a core GIMP feature. Therefore for most cases where it felt needed, the real solution will be to improve the operations' implementations.
