 There are many things that we can tune in producing votes and consensuses
 that will affect the ways that clients use the network, that might result
 in better load balancing.

 We need tools for simulating what happens when we make those changes,
 using data (either historical or live) for the public Tor network.

 We can consider the MVP for this complete once we have a tool that allows
 us to take server descriptors and simulate votes and consensus generation
 using alternate Fast/Guard cutoffs.

 Extensions to this would be allowing alternative consensus methods, or
 other tunables.

 By reducing the cost of performing these simulations we can allow faster
 iteration on ideas that will hopefully allow for better user experience.
