You should always bake the models into clean geometry unless you sell it uncollapsed on some purpose. You probably want people to be able to open the models in various programs and it's not possible to open Cinema specific model in another program so it's always better to collapse it. Also in some cases, you would show people your pipeline or know-how that was used to make the models and it wouldn't be wise to give it away without higher price.
Anyway, people mostly expect you to sell them render-ready model and deformers or other modifiers could complicate it.
