@jan-ivar Eliminating rollback of a pranswer would eliminate a major obstacle to complete implementation of rollback and finishing 1.0 so it's a great idea. 

@henbos We have pranswer because in SIP an offer may receive a sequence of answers, which inform the client of the origins of successive early dialogs that it should listen to. Aside from the state, applying a pranswer has many of the effects of applying an answer in terms of object creation, ICE candidates, media in progress, etc. So as Jan-Ivar says, it's hard to do, and also somewhat removed from the core rollback use case, which is glare.
