There will also be a note indicating that this is due to RFC 5888, in case people later start to wonder where the “MUST NOT” comes from.

Then we must revise 5888.

Its hard to say whether we could get away with making that change 
without dealing with backward compatibility issues.

Maybe we should ask the authors (Gonzalo and Henning) why that 
limitation was put in. It does seem pretty arbitrary.
