@jvalleroy has backported and uploaded the changes in this release 25.9.5 to bookworm-backports as 25.9.3~bpo12+2. This was done on August 12th. So, everyone who has “Frequent Feature Updates” enabled should already have these change now.
Yes. However, if you don’t have these changes, you can remove comments from /etc/apt/sources.list and ignore the slightly incorrect release date shown for Trixie and proceed.
