IMO IProtocolErrorCodeFeature.Error should have been nullable, but the API ship sailed in .NET 5.
QUIC and HTTP/3 errors are variable-length integers that are always positive so -1 can be used to represent unset.

This will be updated to call AbortCore when #35764 is merged.

What does an error code of 0 indicate?

It means the stream was aborted with error code of 0. That doesn't have any meaning in HTTP/3, but it's a valid error code for QUIC.

Can this be created lazily from the RequestAborted property?

I think we still want to stop and complete the output pipes in this situation. So, we always want this event raised, even if someone hasn't subscribed to RequestAborted.
