alt-texts are not necessarily w3 standards, they’re rather a small ‘political correctness’ to people who use screenreaders.

It’s part of the HTML spec.

Provide a text equivalent for every non-text element (e.g., via “alt”, “longdesc”, or in element content). This includes: images, graphical representations of text (including symbols), image map regions, animations (e.g., animated GIFs), applets and programmatic objects, ASCII art, frames, scripts, images used as list bullets, spacers, graphical bumons, sounds (played with or without user interaction), stand-alone audio files, audio tracks of video, and video.
