Sobre la desaparición del criterio 4.1.1 en WCAG 2.2

Web Content Accessibility Guidelines (WCAG) 2.2 está a punto de ser aprobado y una novedad "extraña" es que el criterio 4.1.1 Parsing se considera obsoleto y, por tanto, se elimina. Esto va a originar una situación confusa, porque ya no se cumplirá lo de la compatibilidad con versiones anteriores. WCAG 2.2 avisa de ello en Comparison with WCAG 2.1, donde podemos leer:

WCAG 2.2 builds on and is backwards compatible with WCAG 2.1, meaning web pages that conform to WCAG 2.2 are at least as accessible as pages that conform to WCAG 2.1. Requirements have been added that build on 2.1 and 2.0. WCAG 2.2 has removed one success criterion, 4.1.1 Parsing. Authors that are required by policy to conform with WCAG 2.0 or 2.1 will be able to update content to WCAG 2.2, but may need to continue to test and report 4.1.1.
