Does anyone know of the CA/Browser forum SC81 ballot to reduce certificate validity periods only applies to TLS Server and Client certificate usages or if it applies to all key usages?
This could create a huge pile of churn and toil if it also applies to certs used for SAML assertion signing, which have key usages set for: Digital Signature, Non Repudiation, Key and Data Encipherment.
ETA: paging @ScottHelme now that I've found him here.
