At CMP-12 today's big topic is compatibility of bath fans with AFCI,
in support of expanding AFCI devices to bathrooms, by ACMBA (American Circuit Breaker Manufacturer's Association).

And testing results in support of AFCI expansion to attics, despite the difficult temperature and humidity environment in many attics.

Yes, and they can change their vote, so influence or information after the public input can sway the vote in theory.
Yes the votes at the meeting are not final...not even sure if they record anything other than the numbers at the meeting. When the final ballot is published, you can see how each panel member voted. Also as part of the ANSI consensus standard rules, all negative votes must have a comment. If there is no comment with the negative vote, that vote won't be counted.

While I am not a supporter of the AFCI rules, unless the AFCI itself is installed in the difficult temperature and humidity environments, I don't see that as an issue.

That's exactly the point.
The new requirement is for AFCI for branch circuits for attics.
Think air handlers, whole house fans, water heaters.
The goal of the ACMBA (American Circuit Breaker Manufacturer's Association) testing was to test the actual OCPD devices in that environment. So that would be for an AFCI or GFCI receptacle.

For my money the better move is to put that expensive AFCI in the panel. Then, we need to start shading panels from the sun, as electronics don't last as long when too hot. And frankly a metal panelboard in the sun may be worse off than the attic.
--
There were quite a few sparks at the meeting about the location of the AFCI/GFCI, including a public input seeking to have those devices much closer to the point of use, meaning the receptacle. That was justified based on nuisance tripping requiring a caregiver or senior having to travel down stairs, potentially leaving a child unattended, or potentially falling on the stairs, just to reset a remote breaker.
