To get back on topic, I have not read anything about a change in jumpseat policy in any company communication. I just re-read the FOM on jumpseat and the following is the only thing I can find related to this topic. It's on the first page of Chap. 4.

"The number of seats available to jumpseat riders is equal to the number of
available flight deck jumpseats and available cabin passenger seats in all cabin
classes."

That says to me that a JS'er can sit in any open seat no matter where it is located.
