I've done more reading on the subject. For one thing, the radiometric response function is also called the camera response function. There are (at least) a couple of references to linearization in DNG. Neither of these is related to the RRF.

There are many papers on the subject of inverting or reversing the camera capture pipeline. That is, starting from the RAW file, applying inverse transforms to recover the sensor irradiance at each pixel.

I think that is the kind of thing I'm looking for. So it would appear that a simple RAW decoder—one that simply decodes and decompresses a camera RAW file—neither applies nor unapplies a RRF. That is, unless it's part of some particular camera's inherent RAW processing. However, that does not appear to be the case with NEF, at least.
