Well, more than that, really.

We need to know for each widget what the property is supposed to
contain. I guess this also requires coming to grips with the somewhat
haphazard way in which the acessible tree is different from the widget
tree: sometimes there is a single accessible that 'wraps up' a whole
widget subtree, e.g a button accessible 'hides' the image and label
children of the widget, and instead implements corresponding
interfaces itself. And the same is very much true for the
::accessible-name, which is often taken from 'somewhere below'.

I don't think we can treat that as a first step and hold off on doing
any other fixes until that migration is done.  The migration is a
significant undertaking, and will not be finished for 3.2.

I would say not even that, unless you mean just the handful of a11y
developers. I can't even turn on toolkit-accessiblity on my system;
evolution crashes as soon as I switch to the calendar...
