Thanks. This helps; some follow-ups below.

Sure, that makes sense, but then the view / render code needs to be inside
of the resource objects, not as @view_config decorators, and the simple
wrap-up-renderer way of doing it is gone. I'd have to generate and return a
response object within the model code, which I don't really fancy. Or am I
missing something?

Sure, but we're not using traversal anymore now... we're hand-poking all of
this stuff. I like your solution, in a non-traversal situation.
Can I keep traversal, keep using simple @view_config decorators, and have
file-extensions? Seems like no.
