GetMessageTypes, ListPendingMessages, LostMessage, Received, Send, SendError, Sent, Channel_Text_Message_Flags are now deprecated.
The Tp::TextChannel API completely hides the differences between bare Chan.Type.Text and Chan.I.Messages enabled Text channels, so I don't see how this affects tp-qt4 exactly? Or are you proposing we remove the fallback support for the legacy Text interface from the implementation side?
Andre: What do you mean? Do you think we need actual Tp::TextChannel deprecations (public API concepts which don't make sense with Messages), or not?
Otherwise, let's INVALID this.
