I'm definitely a fan of scene graph APIs.  It'll be interesting to learn
how effective Avalon turns out to be; I'm positive about what I've seen
of it so far.

But even with a scene graph API, you have to decide which lower-level
constructs (shader programs, geometry, rendering contexts, etc.) will be
visible to applications.  That leads you back to the question of whether
you're going to expose the lower-level API or have a new redundant API
that tries to provide equivalent functionality.

And not all content is static; you probably still need a comprehensive
immediate-mode API for things that are dynamic.
