I mean, now that chan_pjsip.c exists, I would very much like to see actually development of chan_sip.c stop and be focused on chan_pjsip.  Reason being, when ever we do refactor / add new features to chan_sip, we end up breaking something.

chan_pjsip is brand new, I don't agree with chan_sip deprecation until chan_pjsip has seen widespread production use for more than a year.  I can understand your concerns about changes to chan_sip, but I feel the risk can be minimized with small changes and tests (see r3172).

Currently 198 out of 736 unresolved bugs in JIRA are tagged with a chan_sip component, most of those over a year old.  I realize this is because chan_sip has plenty of bugs, but they don't get addressed because chan_sip is such a mess.  I think refactoring chan_sip into isolated components will help make it easier to troubleshoot and fix bugs.
