IMO the append_branch() is PITA since ever (ok, it is better since 
branch routes) - so a cleanup is a good idea.

 From flexibility point of view having the append_branch manually is a 
good idea - although it of course will confuse beginners.

IIRC there were also differences between manual and automatic (e.g. 
dispatcher) regarding other branch parameters which were not copied 
(duri, send_socket, bflags ...) - this should be reviewed too.
