Do you mean hard-coded in Radiance here? Such a feature makes sense to me 
also.
In my case the mixfunc for transparancy is consuming lots of rendering time. 
Although .cal files makes the whole system very flexible, some features are 
so commonly used that of course it would be great if these were optimized a 
bit. At the other hand I imagine that these kind of changes are not that 
easily done, if it is possible at all, in the first place.
