No.  I meant that I could possibly arrange to do something like that, 
though.  But only when using 'Make(SomeClass)', not any other kind of binding.

The "by hand" was referring to manually adding the 'uponAssembly' flag to 
any binding that refers to a class with any 'uponAssembly' bindings, and 
doing this recursively upwards through the app.  IOW, the path you've 
already decided to take.

This issue in general is rather interesting.  None of the approaches to 
dealing with it are perfect: it seems there is a distinct tension between 
broad resource discoverability, and lazy creation of those same resources.
