My plan is to add support for something along these lines when we add Path 
primitives in the coming months. (I don't think we should add it separate 
from path primitives because then we'd have to do it twice. For similar 
reasons I haven't yet added "convert text to path" or "draw text on path" 
APIs, or indeed any of the other path feature requests like ellipses.)

However, while there are definitely use cases for hit testing, it's not 
clear that simply hit testing would actually help accessibility use cases. 
Hence the wiki page.
