Building a WCAG 2.2 AAA compliant website, is probably a pain in the ass, if you are doing it using frameworks, etc. not so much, if you're writing the damn thing by hand. The pain in the ass, is writing the website by hand, HTML, CSS, JS and all.
Also, WCAG 2.2 AAA, is almost impossible, if you do not control the markup directly. I aim for WCAG 2.2 AAA for my own website. from what I know, I think I might have succeeded. If anybody wants to have a look, feel free.https://bsteenkampwrites.com
