Re: [DISCUSS] KIP-50 - Enhance Authorizer interface to be aware of supported Principal Types

[Grant Henke]

I understand. My thinking is that since this is a major release, if we are
going to break in anyway we should do it now. Otherwise we will need to
wait until 0.11. The work in adding standard exceptions and
an alternative Java interface should be able to be done in a compatible
manner (deprecating the old stuff for later removal).
