Do you know when the config flag DoNotForceCN will be set to true, so one can use a CSR with an empty common name ?
I need to create a certificate with SAN entries longer than 64 characters and the certificate is created in staging but not in production. The error I receive is “urn:acme:error:malformed - Error creating new cert :: Common name was longer than 64 bytes, was 0” because the line https://github.com/letsencrypt/boulder/blob/25b45a45eca7522bf623a9994cbccdf366adf3b9/ca/certificate-authority.go#L442 in executed and not the line https://github.com/letsencrypt/boulder/blob/25b45a45eca7522bf623a9994cbccdf366adf3b9/ca/certificate-authority.go#L537
Thanks a lot for the hard work.
Edit: In summary, I am asking when the feature described in Certificates with serialNumber in subject will be deployed in production.
