Any deployer using the IdP's private key to secure mutual TLS connections on 8443 is very impacted because it was typically the IdP's signing key used to secure those connections.  The collateral damage in terms of rekeying for individuals is a worse deployment problem but a less significant vulnerability.

I agree regarding the viability of passwords.
