well not changing the subject seems like something we could do without
fuss - not changing the body would likely mean we would (again) get a
number of people asking "how do I unsubscribe", but maybe we will have
to live with that.

As for google/gmail - it seems they are indeed moving towards p=reject
based on:

https://wordtothewise.com/2015/10/dmarc-news-gmail-preject-and-arc/

so we have to do "something" anyway (before June 2016) - I have not
actually studied the referenced ietf drafts mentioned in the second post
yet so maybe there is something in there to help with our usecase...
