Hi @clyang82 Thanks for your contribution.

I think there is no need to make it dependent on an option in the plugin and we could just send the headers always. What do you think @bzwei?

Tests should be updated to check that we send correctly the headers in the event.

I am afraid sending the headers always may break the backward compatibility if someone is dealing with the whole event, including body and meta.

I think there is no risk at all, because we are extending the existing schema of the event with a new root key of the event, preserving the existing "body" key. To me we should send the headers always.

Thanks for your comments. Remove the option to send the headers always.
