I don't know what Devault says, but here is my opinion: do not ship something you don't understand/test/use yourself.

Distros should not package random open source projects they don't use/understand, and developers should not package their project for distros they don't use/understand. For both, it's like shipping untested code and the conclusion is always going to be "you should all run the same system I do" or "we should all have the exact same system, let's implement Flatpak".

Developers should package their project for the distros they support (often that's just Ubuntu). Random people should package the open source projects they want to use in their distro of choice (the more popular the distro, the higher the chance that someone else has done it already). All that under the supervision of distro maintainers.
