Oscar, You are completely right about how this happened and how it should have been avoided. No question of where the fault is, and lessons learned for the future.
We have been talking with IANA and have their guidance. The preferred approach is to change the code point in 7150, but we can only do that if the damage in deployed networks is not significant. Hence the request posted by Robert. If it turns out that there is a cost to changing the 7150 code point then we have to think again. AFAICS, a change to a software stack is annoying, but not much more than a compilation. But a change to a widely deployed network might be a pain.
