True, however, if you add focus and blur you open a whole new can of
worms with browsers.
The very idea of dynamic dropdowns - hiding unneeded navigation whilst
providig it - is just not accessible, as hiding it does not make it
go away.

I listed most of the issues these navigations have here:

A really unobtrusive version of these dropdowns would load in the sub
levels onmouseover vi a AJAX, that way only providing the nice to
have links to those who have JS enabled and use a mouse. On the other
hand I am sure that you can simulate onmouseover with assistive
technology, too.

Therefore the only _real_ solution is to offer a basic navigation,
that only provides you with the main links and the current sub
section, and a "enhanced navigation" that the visitor can turn on if
she wants to.
