But: where do we really need class posing (although I like the
concept)?

I like class posing, and use it in a few places, so I don't want to deprecate or remove it. I would, however, add a run-time check that ensures that every instance variable in the posed class is in the same place as the posed class. I already do this run time checking for mixins an traits, so there's no problem adding it for posing.
