HTML

Modern websites no longer fit the document-centric model HTML was created for. A typical news homepage mixes headlines, images, teasers, and interactive elements in ways the original spec never anticipated. The New York Times even present teasers without headlines at all. This diversity shows how little shared foundation there is for developers today – and why HTML needs a broader, more coordinated evolution beyond isolated improvements.

Aren't such cases already covered? I don't see the issue or alternative.

Unpopular opinion, but this is a bit of a pointless effort. They are never going to get the default form elements to the same level of control/style/design/functionality that web developers need, so JS is going to stay.

Basic form elements are good enough for basic sites, anything more can fall back on JS+CSS bullshit.
