Yes, I will try to prove it on the research so I would like to keep the 
proposal open until the research is finished.

This reason is why it is not recommended to change the default value, 
same as for the MaxCircuitDirtiness parameter, so I will specify it on 
the proposal.

Let me think about it. I will update the proposal soon and I will 
specify how KeepAliveIsolateSOCKSAuth and onion services work with this 
new feature.
