Well, see the second part of my answer to Markus a minute ago.

If we want to have these preliminary terms in operational services we 
should mark them as preliminary when using them, not only in the 
vocabulary list.

And I still think it may be a heavier task for providers to implement 
these  preliminary terms and have to change them several times.

Hence the prototyping idea.
