You're not - you're actually perfectly right.

Radiosity doesn't collect edge proximity information (it doesn't need 
it), only crevice proximity - which I think is the more important of the 
two. (As you wrote, there's always a trade-off somewhere.)

For a full-fledged stand-alone proximity algorithm, I guess a voxel-tree 
based approach would do fine. But that would mean a lot more of coding 
effort - and somputational overhead for data that can't be shared with 
any other features.


(BTW, someone's asking in povray.newusers for advice on your fastprox 
macros... and speaking of them, do you have them for download anywhere?)
