The thing about power-user software is that you can customize and package it to the point where it's indistinguishable from any other software, a polished end-user experience -- the user accepts the workflow of the given configuration and rolls with it, without ever touching the config. That's how some people use Emacs -- they just learn the bindings of the default distribution. But, for Emacs, there are also some distributions like Doom Emacs and such. They are just different user-friendly distros.

What's more, if you have good GUI capabilities (which Mage will have), you could build visual user interfaces for configuration (I don't plan to make such UIs btw, but someone with a good-enough UI sense and interest in this stuff could attempt it at some point, I guess).

If all you do is stick to some distro with some visual config tool, then you won't even have to know it's common lisp (unless some error is signalled and the interactive debugger pops up).
