The above statement is concerning, because section 2.2 of the Baseline
Requirements state:

"Section 4.2 of a CA's Certificate Policy and/or Certification Practice
Statement SHALL state the CA's policy or practice on processing CAA
Records for Fully-Qualified Domain Names; that policy shall be consistent
with these Requirements."

If a CA doesn't update their CP/CPS at the same time as deploying
changes to their CAA policy, they will be out of compliance with the
Baseline Requirements, as GTS was for 90 days.

I was expecting the incident response in
https://bugzilla.mozilla.org/show_bug.cgi?id=1729097 to address
the problem by providing a solution for ensuring GTS' CP/CPS remain
up-to-date with GTS' actual policies and practices.  Instead, GTS's
response is to ensure CPS changes are published by the time of the
compliance deadline that motivated the change.  This would not have
prevented GTS' non-compliance, just limited it to 60 days.  (It would,
however, have prevented their non-compliance from being externally
detectable.)

GTS' response also won't address CP/CPS changes that aren't motivated
by BR/MRSP changes, such as adding another CAA Issuer Domain Name.
It appears that with GTS' current process for CP/CPS changes, such a
change could be delayed by up to a year if it gets "bundled" with GTS'
next annual CPS update.  To reiterate, this would be a violation of BR
section 2.2.  What is GTS doing to make it feasible for them to comply
with this requirement moving forward?

Andrew
