I disagree with you about the compatibility model we should work to
achieve.  I think it is desirable to make upgrading to a new krb5
release very easy for vendors.

If there were a compelling cleanlyness you could get by breaking the
old interface, I'd agree.  However I suspect at least one vendor would
end up shipping both interfaces, and as I mentioned in my first reply
to you I think some similar uglyness is inherent in needing to support
both old and new format errors.

I do think that we need to come up with the new interface though.  And
if we come up with a particularly clean interface for the new plugins
I think it might be desirable to make a clean break.
