<br>
Some CAs do not currently support pre-signed linting so there is
some engineering/coding effort to enable this type of linting.
Unless people have strong feelings about this, I will leave the
proposed dates unchanged.<br>

I didn't read the requirement to imply that ALL the requirements of

<p class="MsoNormal"><br>
I see two issues here:<o:p></o:p></p>
<ol type="1" start="1">
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l1 level1 lfo2">
Require linting with either a phased-approach or directly
with a single effective date: I'm fine with either approach
with a slight preference to the phased-in. CAs should have
been following public incidents and m.d.s.p. discussions for
years, so existing CAs should already be doing pre-sign
linting. OTOH new CAs need the additional guidance. A CA
will either have to create its own technical tools to check
their profiles accuracy or use the recommended open-source
tools we reference.<o:p></o:p></li>
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l1 level1 lfo2">
I'm fine with the stated preference for pre-signing over
post-signing linting but the post-signing linting should not
be "NOT RECOMMENDED" because it doesn't do any harm on its
own. The fact is that we must clearly state that the
pre-sign linting is mandatory and the post-sign linting is
optional.<o:p></o:p></li>
</ol>
<p class="MsoNormal">With that said, Ben and Corey have agreed
with a SHOULD effective date of 15 September, 2024 and a SHALL
effective date of 15 March, 2025. If people have objections to
setting these effective dates, please let me know.<br>

<span style="font-family:"Arial",sans-serif">Is
it worth more clearly establishing expectations for
the evaluation and, when applicable, deployment of
updates made by or to linting tools. For example, can
we establish a reasonable expectation that within
30(?) days after an update has been made to a linting
tool relied upon by a CA, it has either (1) been
adopted in the production issuance environment - or
(2) considered not applicable given the scope of
recent updates (for example, if a CA only issues DV
certificates, and the most recent update only pertains
to EV certificates, there is no expectation that the
updated version is deployed).

</ul>
</div>
</blockquote>
<p class="MsoNormal"><br>
This may open a series of questions around updates in other,
more security-critical components of the CA pipeline. I think
we should address this issue more holistically as it affects
updates to hardware firmware, OS patches, CA vendor software
updates, third-party software dependencies, switches/router
firmware, and other dependencies in Certificate Management
Systems.<br>
<br>
It is also challenging to define what an "update" is, at which
level (major, minor version), etc. I would prefer leaving that
out of this particular ballot and let someone else address it
in a separate ballot without risking the speed and success of
the linting ballot. I hope this makes sense.<br>
<br>
More feedback is welcome before proceeding with the changes.<br>
