Support NewDecoder?

No plans at the moment to implement a streaming interface. This lib isn't very efficient and needs to run through all the YAML up-front anyway, so I'm not sure it'd work well.

Do you have more details on the use-case? Perhaps I'm missing something.

Oh no rush. It's simply that yaml.v3 provides it so I'm relaying the issue here as it should come in handy at some point.
