The following interfaces do not have low-level bindings generated and are not drafts:
Chan.I.RoomConfig1, Chan.I.Room2, Chan.I.SMS, Chan.I.Subject2, Chan.I.FileTransfer.Metadata, Proto.I.Addressing
Branch at URL attempts to fix this.
Branch updated again removing the generation of low-level bindings for Chan.I.RoomConfig1, Chan.I.Room2, Chan.I.Subject2 that are versioned interfaces. We still have to decide what to do with versioned interfaces to avoid breaking ABI when updating to new versions before generating bindings for them.
Bug #43592 was created for the versioned interfaces.
Olli reviewed this at IRC, branch merged upstream. It will be in 0.9.0.
