We will not be > supporting this or a "multilib" usecase. The aarch64 kernel can execute both aarch64 and aarch32(fully compatible armv7) binaries. For example, the kernel of raspberry pi 3 is aarch64 and fedora arm version can't run on rpi3. Even all binaries can run on it but only dnf command can't do that.
