email often has DKIM headers, which are fantastic for non-repudiation

Why? You can rotate your DKIM keys daily and there is nothing that'd prove that you used any particular key at a given time.

To some extend, the fact that gmail accepted a message indicates the email passed DKIM inspection.

Only if it had strict DMARC policy (reject) at the time of sending. But it's not possible to reliably check old values from the past. No policy or quarantine policy makes the email go to spam, that's all.
