Some elements are not focusable by defaut (e.g. <div>) but if we want to be
able to focus them via Javascript, we have to have a way of adding them to
the stack of focusable elements in the page. This is the way I understand
the basic functioning of Jeremy Keith's Hijax:

myElement.tabIndex = -1;

Considering how we're still stuck with older UA's for quite a long time
(thus knowing that ARIA's rudeness attributes will be copiously ignored),
being able to address accessibility issues in these as well would force us
to, indeed, keep the possibility to add a tabindex property to any random

So it's not so much bogus as addressing older user agents and is a bit
larger than widgets per se.
