Ballot SC23 v3: Precertificates

Purpose of Ballot:

This ballot intends to clarify requirements placed on Precertificates in BR
section 4.9.10.

During a lengthy discussion on the mozilla.dev.security.policy forum [1],
it was discovered that BR section 4.9.10 combined with BR section 7.1.2.5
prevents a CA from responding “good” for a precertificate. This is a
problem because there is no guarantee that a certificate corresponding to a
Precertificate has not been issued, resulting in root store policies such
as [2] that require CAs to treat the existence of a Precertificate as a
presumption that a corresponding certificate has been issued and thus that
a valid OCSP response is required.

This ballot intends to resolve the problem by clarifying in the BRs that a
CA may provide revocation information for the serial number contained in a
Precertificate.
