Seeing how the git repo mentions MyFamily management, I believe it's just #1 in
this case.

I remember reading someone describe their setup of #2, with a TCP load
balancer in front of multiple Tor instances all using the same fingerprint.
Outright my reaction was that this is fundamentally broken and cannot work,
but apparently it does. Still, IMO that's easy to get wrong and unknowingly
degrade the network quality for Tor users.
