When you look into a common packaging format, it turns out that what you really want is common packaging policies. The packaging software is not relevant when you try to install something for one Linux distribution (be it Debian, Fedora or possibly Android) on another where it doesn't hook into configuration scripts, enable services, set up firewall rules or desktop icons as the user expected. Whereas something like Debian "just works" for the end user.
