Comment (by teor):

 > As for using different IP addresses for each transport, sure, why not?

 But since the user can only set one value for each environmental variable,
 we should treat an unqualified address as applying to every transport that
 isn't named.

 So we would end up with something like:

 TOR_PT_OUTBOUND_BIND_ADDRESS_V4=obfs4-0.0.0.0,snowflake-203.0.113.4,203.0.113.2

 I'm not sure if we need this level of complexity in our implementation?
 We could put transport-qualified addresses in the spec, but avoid
 implementing them until we actually have some demand for them.
