I'll tell you what I want: I want Google to help identify non-DKIM-compliant forwarders. As the operator of (yes, I know) a vanity e-mail domain with DKIM, SPF, and DMARC records, I have no problem sending mail to gmail directly; in fact, my outgoing mail uses postmark, so I'm not even directly responsible for my sending reputation.
BUT! It drives me crazy that many of my recipients get e-mail at hosts (schools, mostly) that forward the e-mail
with differences (encoding changes, subject changes, etc.) that invalidate the DKIM signature. Since they're forwards, the SPF check is going to fail, too, so the end result is that google shoves it into a spam folder.
I claim that google definitely has the data to be able to identify these bad forwarders--heck, even mail sent from gmail to these hosts will presumably fail DKIM checks on the way back into google--and I'd love to see them contact these domains, or even publish a list of known bad forwarders, so that I can push them to make changes.
