Seems to me that a "purist" printing approach is mainly for the benefit of the printer. The viewer doesn't know what was done unless things are carried too far. Or the printer tells the viewer what his process is in an attempt to influence him. A big factor is how you print concerning light/dark and hard/soft. Sometimes things carried to extremes work well. But personally I think that a strong image printed in a matter of fact way is best. A print that causes least attention to the printing. And I guess you could extend that to photographing in a way that uses the least drama.
