T232 affects qubes-whonix.
Due due qubes-whonix 9.6 using packages whonix-repository and whonix-setup-wizard that are affected by T232, users will run into issues when attempting to upgrade from 9.6 to higher versions.
qubes-whonix users are using the the literal stable code name in /etc/apt/sources.list.d/whonix.list, which this repository is no longer in use. It was last updated for Whonix 8,
To let users qubes-whonix 9.6 users do binary upgrade, they also have to be told to use at least once sudo whonix_repository --codename wheezy beforehand or we need to get the repository with the code name stable up again. The latter would break systems of remaining users of Whonix 8 that are still having the stable repository enabled (because 8 -> 9 upgrades were kinda "bumpy"). But since Whonix 8 is no longer supported for a long time now anyhow, that would be acceptable.
I somehow knew it wasn't ideal to derivate from Whonix default package selection and to sneak in features into the stable that are purposed for the development version.
