I have to say that sounds wrong to me.
I've had a few Aussie coffees that we spec'ed to that sort of age - but they all had robusta in them and the "excessive" aging was a result (and of course the robusta "protected" the appearance from degrading with that age).
Now... to be fair, just 'cause one roaster has switched some of their espresso blends to that sort of suggestion and another has one blend that fits the parameters doesn't actually support the earlier claim that this is "the prevailing custom" in commercial settings.
Mostly, it sounds wrong to me too. But here's a thought. Italians made great tasting espresso from very low quality coffees, rubbery Robustas, rioey Brasils, and fermented Ethiopians. They used all sorts of tricks, aging the coffee, grinding ahead, sacrificing the first or last drops, etc. etc. When espresso became a specialty drink in other countries, better coffees were used and these tricks were abandoned. But what happens when you use really good coffees, high grown coffees with lots of acidity or other aggressive flavors. A light roast, ultra fresh, may just be too overwhelming as an espresso. So maybe all the tricks that took the edge off the funk of monstrously bad coffees need to get rolled out again to take the edge off the power of monstrously good ones.
