I'm 99% sure that Phill is correct here. We discussed "suicide notes" in PKIX a few times over the decades, and I believe we never came to any conclusion. If such a format has been standardized, I can't find it easily by searching.

In a world where you might have bought a certificate from a CA or, in particular, a reseller with whom you might no longer be able to communicate (such as if they go out of business), being able to create a signed request with proof-of-possesion of the private key would be a valuable feature for the Web PKI.
