Tor is a form of gravity well. If the cloud is not saturated,
adding more nodes increases odds of traffic analysis.
Among other things, tor's utilization falloff curve should probably
not give many users and use cases much comfy feels.
Tor's design doesn't provide a way to distributively utilize excess
nodes safely, it cannot, so it tries to game and manage that as
best it can. Such global throttle could help, but access to throughput
will disappear, and it's still subject to same class of analysis.
Tor's design can't really do much here while still being called tor.
Look elsewhere for other designs.
