Interesting. Definitely a challenge if accurate emulation of film stock is desired. I almost always add a subtle amount of "grain" with LR when developing photos. It looks pleasant and seems to add a sense of coherency to an image. I find that in many cases where details are lost to aggressive NR or otherwise simply not present, grain can make it easier to "see" the missing detail... as with most things, the optimal amount of noise is not zero.
