Thanks, that was very helpful!
It's working fine when you create shader nodes in the render tree, but it
doesn't apply to Get->Material->Architectural, the node you get from that
still uses the old defaults. Is it a different callback?
Anyway, here's what I came up.

oD = in_ctxt.GetAttribute("ShaderDef")

# Return value is ignored as this event can not be aborted.
return true
