Remind me of that day of Yagudin and Plushenko and salt lake city olympic where the medalists do 3-4 quads. I think it is good for the sport, good for the field. I actually root for him because some US fan and judges have been acting like they are too good for quads and it is destroying FS and what makes the sport special is the art and emotion and bla bla bla. Now I just want to gloat over the reality that their no.1 guy is a young quadster lol. 
It's easier for him because he has long set-up for his jumps and doesn't really put much steps before, but he rakes in from just the base value of landing them all. Also, he's been used in doing 4-quad lp since last season. What his job is to stay healthy and keep his peak for the rest of the season. The biggest question mark on him is the few times he skate to the second half of the season, he doesn't do as well as Nats. Like Yuzuru, he tends to peak mid-season. 
But then again, Nathan has surgery last year and sit out the 2nd half of the season, but suddenly came back with both 4lz and 4F so looking at Yuzuru I don't see it being included to be that impossible at all.
If he's not clean, sure. But we have always known Yuzuru has to skate clean. He has a far more complete, more difficult program and this season is far from normal, with the way he had to be off ice for so long so I'm not surprised he has yet to show us a full, clean H&L. He's got a new quad with higher BV as backup being ready for next season. I still don't see what has changed all that much compared to before USA Nats. We knew Nathan was coming and where he'd be if he got consistent and so did Yuzuru. Nathan's PCS here were massively inflated (some 6 points compared to GPF in the FS) and he's still not hitting Yuzuru's max score. Let's wait for 4CC to see where Yuzuru is at.
As for skating itself, honestly I kind of agree with lucky strike. He thinks 3 quads and any more it affects the artistry. Personally I say four is doable, having seen Yuzuru's H&L but past that I do think it's severely affected, especially for skaters like Nathan. While I am a great fan of jumps as this is a sport, I also don't want the other side to be lost as it's not figure skating then which is an artistic sport. Though who knows, PCS are slowly losing in importance so maybe we will end up with jump fests and superficial covering of those by some hand waving. Not that I'd watch that but maybe. Anyway, I'm not worried
a whole special medical team for him. I know Japan isn't going to do that given the depth of its field and maybe there are issues of fairness.
I kind of want for Yuzu what Korea did for Jun-hwan
