A viable way to install something that works on all Linux distros (and Mac!), and doesn’t require root.
Nix portable installations, Soar.
The reason people use curl | bash is precisely so they don’t have to faff around making a gazillion packages.
Developers shouldn't be making packages. They do things like vendor and pin dependencies, which lead to security and stability issues later down the line. See my other comment where I do a quick look at some of these issues.
