Allow me to ask for clarification.

- "receiving_domains" has been proposed in #23 as new metadata.
- "receiving_domains" is redundant to "envelope_to", which already
exists in RFC 7489 and is being used in practice by a small portion of
reporters.
- Privacy concerns have been raised, which apply to both elements.
- The proposed "receiving_domains" gets rejected.

What happens to the existing "envelope_to"?
