It would be nice if Ubuntu pruned dead / barely working products from their repos. There's an astonishing number of frustratingly bad audio apps in their main repo.
I'd say that's part of their issue, the other side is that they don't seem to track the development of projects all that well. In some cases this simply is shipping old versions with known and long fixed bugs and in other cases they miss the evolution of various projects as maintainers change over. The latter case includes some abandoned/nearly-abandoned standalone tools getting converted to plugins (generally LV2) and receiving more active development.
More active package repositories such as kxstudio seem to resolve at least some of this friction.
I think this has to with community. The Arch community moves pretty fast and forces users to go look up packages online and comment/vote on their state which results in packages being both promoted to default repos and getting thrown out of the default repos.
