I’m going to assume this is a joke. However, if it’s not a joke, no. We as a community have gone to great lengths to use responsive design over the past few years. There are still styling cases for complex elements that can’t be implemented without JavaScript. This is just an additional step of the journey to allow intermediate styling for complex cases.

If anything, it should enable (minor) expansion of noscript!

Id actually like to redact that prior message and think further, here. We already have information egress thru URIs, with some amount of “protection” via CSP. But I didn’t think of other types of attack vectors at length. Someone above remarked that this is just a general form of conditional, which perhaps unlocks new vectors. Im always surprised by CSS so i should slow down and keep an open mind :)
