I tried to do this in 2022 and there was a comment about the spec normatively referring to the HTML 5.2 Autocomplete list.

WCAG 2.1 still explicitly mentioned HTML 5.2 in the note for https://www.w3.org/TR/WCAG21/#input-purposes

However, WCAG 2.2 no longer does this https://www.w3.org/TR/WCAG22/#input-purposes and just references versionless/living standard HTML
