For the trixie release notes, especially for the “Upgrades from Debian 12 (bookworm)” section, it probably is a bad idea to change the .gpg file extensions to .pgp as the changes to the .pgp file extension for the files in the filesystem was done in the trixie release cycle and is not present within bookworm. The Upgrade from bookworm fails with .pgp in here. btw: (And this is not a GnuPG artifact, but an OpenPGP one. :)
If this change was rushed because of the GnuPG vs. OpenPGP controversity, please revise this kind of emotional changes. And please do not add an updated package to old bookwork just to show us that .pgp is yet the one to get used here and .gpg is bad. That probably will have other side effects and unforeseen drawbacks... There's nothing wrong with having the .gpg extension in the current upgrade guidance and to change this with the next or one of the upcoming releases. Thanks hede
