I think we need to be careful with terminology here - what you describe above is not LLU, but rather the Unconstrained UBS with the upstream speed limit removed and the prohibition on supporting real time services taken off.
With LLU, then ISPs can set their own upstream limits, can they not? At the moment they take what Telecom gives them. If the ISPs can't change the upstream speeds, I don't quite see the point of LLU.
