Right – that’s because we haven’t updated the EVCS to reflect the CS discussions.  That would happen after passing the CS BRs.

Apologies for not reading these in detail until four days after the deadline.

I am concerned that it seems that EV Code Signing certificates are not
a super set of standard (Baseline) Code Signing certificates.
Specifically, EVCS section 9.2.2 forbids subject alternative names in
EVCS certificates while the BRCS section 9.2.1 requires a SAN.
Similarly, EVCS 9.2.3 indicates common name is deprecated but BRCS
9.2.2 makes it mandatory.

My expectation is that EV certificates always meet the requirements of
the non-EV certificate such that systems that don't differentiate
between EV and non-EV certificates can use EV certificates as standard
