It makes sense; the vibrassae have nerve endings and are a sensory organ, so it would be better if they were left alone. It's only a minority of breeds that cut them off anyway; for breeds with very hairy faces which are shaved (poodles etc) it would be difficult to avoid removing them, but otherwise there's no need.
Some people do it in the USA because they think it makes the muzzle look cleaner, but it's a completely absurd practice in breeds where the face is not cleaned/shaved/etc. in any other way. I wouldn't say it's dying out in some breeds sadly. In a dog with a light muzzle and dark whiskers it might make the muzzle look less clean up close but I have yet to see a dog that had an advantage in the ring due to a lack of whiskers. It certainly won't help them perform their intended function more effectively.
It's not news--I think it must be 3 years ago or so I heard this. I know some people in our gundog breed still do this, but personally I think they are far better left alone.
I have to say that on breeds which dont have their faces clipped, I agree. I know some that do clip whiskers off in my breed but personally I dont see...excuse the pun...that they are a problem to be left. I like to see them on as it makes the face more attractive. On breeds like poodles who have their faces clipped, it isnt possible to leave whiskers, therefore hard to enforce.
