Kind of interesting actually. In the 2000s/2010s it was quite normal that distributions provided modified packages. Maybe not necessarily function-wise but theming, config files to a degree that interoperability wasn't the best. Even more funny that this is done now by Debian which always had a reputation of providing vanilla packages... But I guess after the xz debacle this is getting a new kind of attention
If this was the first time they were packaging keepassxc, this would be fine. If they instead chose to remove the keepassxc package and provide two new packages, keepassxc-minimal and keepassxc-full, it would be fine. It's the fact that the main package that people already have installed will no longer have functionality that many users depend on, breaking their configurations after an update.
