That sounds really interesting. This will allow one to, for instance,
introduce persistent vocabularies which include their own translations
internally. Right now doing so is quite unconfortable, given that titles
are returned with terms, and at the time they're computed, the
vocabulary has no direct access to the request to compute the
preferred language (one may use interaction.participations, but that
looks like a workaround).
