No.
Not at all. I think that is a good idea.

- question for the dev team:
is there any information provided in the execution context that
could inform a plug-in that its inside an iterator? the
documentation doesn't indicate any, and if there would it allow
state-saving patches to 'do the right thing' automatically.
It's possible to do this by using some unofficial API calls, but
that's probably not recommended. It's not overly difficult though,
mind you. Alternatively, you could have the patch track the times
that it's executed at, and if subsequent executions have duplicate
times, you're inside an iterator. I don't necessarily think that's
a good solution, but it's one that would work without any hacks (it
also requires applications to fill in valid timestamps when
rendering).
As a general extension to this idea, I've run into a number of
instances where graph hierarchy introspection would be wonderfully
helpful; doing the Right Thing in GLSL patches is different if
you're not in a GLSL patch; sometimes knowing what parent 3D
patches (lighting, fog, trackball, among others) can help you do
less work depending on what/how you're rendering. So having a way
to find out if you're "inside" a given set of patches, and then
finding that patch's (or patches') parameters would be helpful in
those cases.
Is that too over-the-top?
