With all due respect viahorizon, I do not think that that hyperlink shows any conclusive evidence that Raw Developer is actually able to pull more detail from the displayed photo. What I'm seeing is that Raw Developer is simply leaving in the uniform noise pattern which covers the whole photo, although I believe you are very correct to say that LR removes some of this very fine noise. However, when looking at the actual detail present in the photo, I don't actually see anything extra in the Raw Developer crop. All that is missing is the very fine noise, which should not be apparent in actual prints. Unlike previous versions of Lightroom, I think that 2.3 has a beneficial amount of this effect- it does not actually remove real details if you pixelpeep (which, in my opinion, is the necessary response with the nature of your request).
By doing this small amount of noise reduction in the demosaicing, it actually allows photos to be sharpened more without having to sharpen the micro-noise, which has no significant benefit in real-world terms. Additionally, when this would actually be significant is when the photo is being interpolated for large prints, but in that stage of the workflow adding a fine layer of monochrome noise (or "false detail" as Photozoom Pro puts it) will restore that impression of micro-detail, if the user wishes. I think that too many people are incorrectly identifying what they are seeing in 100% crops of LR conversions- I believe Jeff Schewe might agree on this point- and that if you are really that concerned about it, you are under no obligation to use Lightroom. What some people identify as a disadvantage is actually an advantage when Lightroom is used well in conjunction with its sharpening, which is actually pretty good IMHO. I think it was somewhere on this site that I found a user's approximations of Photoshop's PK Sharpener Capture Sharpening presets, which is a really good starting point to get familiar with ways to sharpen the LR files.
It's all a matter of taste, I know, but it is very easy to re-add what you are mistaking as micro-detail later in the workflow by adding a monochrome layer of noise. What deconvolution routines do, such as FocusMagic, is that they enhance the grain-- it is yet another way to visually create the impression that detail exists when it is the enhancement of grain you are seeing (which is why deconvolution can make high-ISO pictures look damned ugly by enhancing the noise). I think deconvolution techniques can create some great effects with low-ISO pictures, and it is something that is requested every so often for new features (I have requested it myself in the past), but LR capture sharpening can actually do a pretty good job if treated right, and you understand what you are seeing at high magnification.
