This was an old discussion (back to 2013). Julia would not have been accepted in the official openSUSE repos if everything was bundled. In the beginning, even LLVM was not bundled, but this caused some weird bugs and I could relaxed this.
There are many problems when you bundle libraries regarding security. openSUSE Leap, which follows SLE, must be every stable and secure. Hence, this is very unlikely to change. Leap 15.1 will have Julia 1.0 and all other point releases. Tumbleweed will always have the latest version.
As far as I know Arpack still doesn’t work with the arch linux julia package.
This is pretty important for a language designed for scientific computing I think and in consequence I can only use the binaries provided by the official julia website.
