One key frustration is it’s typically not possible to have an arm distribution that boots across most arm boards, because they have incompatible boot loaders. Ie you have a raspberry pi image and a banana pi image and an orange pi image and the rock pi S image that are all different from each other. There have been some attempts at UEFI on arm that would address this, but it’s nowhere near as consistent or compatible as on the x86 platform side.
