FWIW, the attribute used to be called "irrelevant". It was renamed to "hidden" to align with ARIA that has "aria-hidden" for the same semantic.

HTML5 "hidden" is mostly redundant with "aria-hidden". It provides three differences:
 1) "hidden" will eventually have UA style sheet support.
 2) "hidden" in theory applies to non-accessibility unusual modalities while "aria-hidden", in theory, only matters to accessibility API mapping.
 3) "hidden" is part of the host language on the principle that ARIA is a transitional solution and should become syntactically obsolete as host languages gain enough features to address the use cases.
