As a user, I would love to get rid of curl | bash and use the OS package manager instead. This would actually be more convenient to me: I wouldn't have to hunt through the documentation to find out what was installed, where it was installed, how I can update it (or does it register its own auto-updater?) and how - or if - I can uninstall it again.

This seems more like a convenience for certain software projects who can't be bothered to interact with distro maintainers and instead want to circumvent the distro system entirely.
