I imagine the main use-case where this sort of behaviour might be expected is a Javascript application which dynamically adds a new form to the page based on some user interaction and one of those fields should be autofocused when it's been added to the DOM.

Is it not possible to say the autofocus attribute is readonly? It dose 
IMO not make sense to apply it via scripting, as focus() is available 
for scripting.
