Actually the reverse is true currently, while with the introduction of the
main element we have html elements that depending on context of use can
represent all of the landmarks,
browser implementations are still incomplete[4]. Using ARIA in HTML [1]
provides guidance on which elements benefit from the addition of an
explicit role

AT and authored skip links don't actually work like this, for a skip to
main content link a referenced element is required, one which identifies
the start of the main content . As Rich Schwerdtfeger (who developed ARIA)
recently stated in relation to landmarks[2]:

Probably the most important rule for applying landmarks is to ensure *all

and as the semantics applied to HTML elements such as nav/aside etc are
defined in terms of ARIA landmark roles, it underscores that role=main and
the <main> element are integral and necessary.
