I have done some investigation, and yes I can't see any substantial changes.
I did wonder if it was calling the anon-node aliasing code, as that's new,
but on closer inspection it looks like RDQLLocalModel shouldn't do that. So
no obvious explanation.

Well I'm no longer on the project, so probably not best to defer to me on
this, but FWIW I think the approach you suggest is reasonable for now.
