I am reluctant to add ad-hoc properties without a sound technical 
rationale. And yes the information leakage *is* a concern.

Can you explain what you are trying to do?

connection.redirect and the known_hosts field got removed because they 
a) duplicate what load balancers do much better, and b) don't work in 
many network setups since they rely on the clients to be able to resolve 
servers by their internal names.
