That's not the intent of the document/tables.  That is, it is only (1) 
saying what UA 's are to do with aria-less elements when publishing 
information to the a11y API, and (2) restricting authors in terms of 
their use of ARIA.  It does not direct UA's to add aria roles, states, 
and properties to the DOM where none have been given.

I suspect UA's are already doing the element -> a11y mapping already, 
carried over from the time before aria.
