You're also remarking blurry resolutions. For that, there is the tv media. The problem were discussing is the lack of safe/unsafe area support, which is another one.

And now it seems to be a problem that is pretty narrowly focused, mostly on authors creating content/pages/widgets specifically for TVs, for maybe the next 5 years or so (my guess as to when SDTVs might become irrelevant to that group of authors). Is that accurate? Do we agree that most general Web authors aren't going to care about unsafe areas? I'm not saying that this isn't or is reason enough, I'm just trying to understand the scope of the issue so that we can evaluate it in that light.

Because not having a CSS media query would require browser sniffing to decide whether to apply the safe area or not. I did mention that the safe area might exist or not, depeding on cable used, type of TV, where the user agent runs and other unpredicted conditions. It could run on an external device or on the TV itself. But I'm repeating myself.
