That. Historically, upsteam provided sources, and downstream distros packaged it however they want to. If anything, the developer would package it for their own use on the distro(s) they use.

Is it weird for the users? Kind of. But it still makes the most sense: you can't expect the developers to know how to properly integrate a package in every distro. And what usually happens is that we end up with packages that ships static binaries and puts the app in /opt and call it a day.

I'm an inactive maintainer for [The Lounge](https://thelounge chat), and the result of us trying to package for multiple distros is that we store chat logs in /etc/thelounge because the project is designed mostly for the Docker version, which uses just one "data" folder. The project prefers consistency for the users, so the deb and Arch packages are both fairly questionable. I get reports for this from time to time in the AUR comments, and I'd have to step over the other project maintainers to split it into /etc/thelounge and /var/lib/thelounge as it should. If packaging remained independent, I could adapt the package better for Arch's FSH.

The universal platform for developers that want to offer end users a prepackaged way that works on every distro is Flatpak. Personally I prefer to install natively where possible, but I think it's a good middleground between users having to figure it out, without developers stepping over the distro's package structure. Users that want a native package can get good quality ones or build it themselves, while less experienced users can just use the developer-supported installation method.
