The W3 validator currently flags this. One problem area is tables where you sometimes need an explicit role=table to override layout table heuristics which act like an implicit role=presentation on some tables: https://www.powermapper.com/blog/layout-tables-vs-data-tables/
There's an issue on html-aam for the role=table problem: https://github.com/w3c/html-aam/issues/293
Edit: it's worth finding out why this is NOT RECOMMENDED - I think it caused problems in some browser a11y tree implementations.
While working on #2084, I found this bit of ARIA in HTML:
From this, it feels like it would make sense to have a rule checking that, since tools are expected to fail it. OTOH, this rule would only be a best practice, not even mapping to ARIA in HTML, since this is allowed but not recommended 🤔 We're not really having any of these currently…
So, should we have a rule to check that the explicit role is not the same as the implicit role?
