Slight oxidation is a hallmark of "Real Ale". While I haven't been to England, I have had cask ale from a few different breweries that are known for getting the British "IT" right. Cask ale will oxidize, it's expose to the air after all. But time that oxidation right, and it smooths out the beer very nicely.
If you're going for an American "Hops and malt to 11" beer, no, that oxidation isn't going to help. But a smooth, lightly carbonated pint? Works great.
Also, I doubt fresh hops would work well in certain Belgian styles...
