i think one of the greatest changes to web accessibility would be to:
create an image format or extension to a format that supports alt text natively
make screenshot tools automatically pick up the text (actually finding the text in the elements inside the screenshot, not though OCR) and embed it into the image
make it into a js api so sites can customize it to whatever formatting they like
90% of social media is screenshots so i'd image this would be a massive boon to many people
