You guys are crazy! I mean, it works, tons of people do it and if there were as many issues as you seem to believe, then people would report that!
I do wet printing from stand developed negatives, and they are fine! It's not like some unquantifiable element of the quality is lost, which is what it seems you are saying. The blacks are black and the whites are white, and the only issues are the edge effects which can get a bit crazy for pure stand developing, but are neutered if you shake once in a while. And the different appearance of grain, but that is something some people are looking for.
Stand developing does work, but it works in a way that is at least slightly different from the type of developing that the films and developers are designed for.
In my relatively limited experience, it also is a bit more inconsistent than "standard" developing.
Personally, I don't like the effect it sometimes has on mid-tones, and I think that mid-tones are what make or break a negative.
There is another thread here on APUG where we are discussing Kodak's recommendation for an EI for TMY-2 in HC-110. The recommendation uses the word "optimum". And the analysis of "optimum" includes things like how shadows, mid-tones and highlights are rendered in a negative. Stand and semi-stand developing tend to skew that rendering.
I am much more likely to use it as a special purpose technique, such as when I need a compensating effect, or when I'm in a mood for edge effects.
If someone likes the skewed results it gives, they should feel free to use it. What concerns me, and I think concerns Gerald and others, it that we see recommendations for it as a general purpose technique that seem to be directed toward people with very little film developing experience. And we don't think that it is a good place for inexperienced people to start.
