Hopefully it's been good for other people... I haven't seen any benefit personally. :\

On a related note: do you know if DMARC feedback leaks information to the sender on whether or not you opened an email, or reported it as spam, or similar? If so, do you know why this isn't considered a privacy or security issue?

DMARC feedback is only based on the MTA (Message Transport Agent) handling the mail. I don't have much experience with DMARC reports but Senders typically use it when they are first Setting up DMARC. It is up to the receiving MTA to send the inbox/spam result according to the RFC. I think that the reports are aggregated so single inboxes are not able to be detected. I don't think many people actually send / follow up on DMARC reports imo.

Recipient activity is not part of DMARC, so there are no concerns there.
