I don't think that it's ridiculous at all.
What would make it so?
The carry over the ridge? There are hundreds of holes of the same length with water fronting the left side of the green. This hole might be slightly more penal, since you have to have some air under the shot to get it over the rocks, instead of just sufficient distance, but that difference is pretty marginal.
The blindness? Here, I actually think that the length of the hole makes the blindness even less of a problem. The hole is only partially blind: you can see half of the green, or at least a big chunk of it. It's easy to figure out where the pin is if you can't see it. And because it's a long par 3, you aren't expecting to get the ball into birdie range anyway. You can see the front right edge of the green and can play to it as if the ridge were not there. That's a fine way to play the hole for almost all of us. And if you want to try to sling a hook back to the left side, nothing about the hole prevents you from trying it. Sure, it's a hard shot; but it's a hard hole.
The bottom line for me is that there are a slew of ways to make a three on this hole. You can hit to the right-center of the green. You can hit to short of the bunker and, from what I can see, have a long but straightforward chip. Or you take a risk to give yourself a chance at a short putt. It seems like the kind of par 3 that we could use more of: a hole where it actually takes some cajones to shoot at the flag and where there are plenty of other ways to get the score you want by playing away from it, or even away from the green altogether.
(Take everything I say with the caveat that I've never seen or played the hole and don't even know where it is -- so I could be misreading what I see in the pictures something fierce.)
