I want the web platform to make accessibility compliance easier to achieve

Building accessible web experiences is one of the most time-consuming and technically demanding aspects of modern web development. Meeting Section 508 standards (and WCAG more broadly) requires juggling a multitude of tools, techniques, screen readers, and combinations of ARIA roles, attributes, and properties — many of which interact in non-obvious ways across different assistive technologies and browsers.

I want the web platform to significantly lower the cost of achieving accessibility compliance. This could take several forms:

• Better browser DevTools support: Built-in accessibility auditing and real-time feedback during development, surfacing missing roles, incorrect ARIA attribute usage, and contrast failures without requiring external tools.
• Smarter defaults: HTML elements and browser UA stylesheets that handle more of the accessible-semantics heavy lifting by default, reducing the number of manual ARIA overrides developers need to apply.
• Clearer platform guidance: Browser engines providing actionable warnings or suggestions when semantic markup patterns are incorrect or incomplete, making it easier to understand what combination of attributes is actually needed.

The goal is a web where building accessibly is the path of least resistance — not an arduous compliance exercise requiring specialist knowledge just to meet a baseline.
