IMHO, if it's not documented but used then backward compatiblity should not be
an issue. If it's documented and some featured bug is being exploited then
backward compatibility should not be an issue. If it's documented and used
correctly then backward compatibility is a must.
Also, IMO, backward compatibility doesn't need to be automatic. It can be
provided for by a switch or even by a separate set of macros in a iberty.m4
file or both.
