The thing is terminal tools are already available.
Right, after many years of Linux, I get the feeling that developers assume that if you don’t like text-based input, you are not responsible enough to configure your own computer. It strikes me as a hacky workaround to the problem of different knowledge levels among users. This is not a criticism of any particular developer, and I have a deep respect for them all. It’s just an observation. UAC is not much better, and Apple’s “solution” is even worse.
