where we're trying to work out enough measurement/evaluation/simulation
infrastructure to answer the question "If we drop all the relays with
capacity less than X, total network capacity goes down but speed goes
up. What does that look like for various values of X and various network
loads?"

If you want to go even deeper into the research, check out these recent
tech reports that explore splitting circuits into multiple paths to take
better advantage of smaller relays:
