We will completely remove Mplex in v0.24 as it makes protocols very bad to implement,
if you are in this situation you need to add yamux support to your other implementation.

#### Gateway: meaningful CAR responses on Not Found errors

When requesting a CAR from the gateway, the root of the CAR might no longer be
meaningful. By default, the CAR root will be the last resolvable segment of the
path. However, in situations where the path cannot be resolved, such as when
the path does not exist, a CAR will be sent with a root of `bafkqaaa` (empty CID).

This CAR will contain all blocks necessary to validate that the path does not
exist without having to trust the gateway.
