Re: PROPOSAL: Repurpose one key and reserve it for third-party packages

I'm not sure I understand the difference, and for most users Emacs is not 
an "interactive computing environment", it's a text editor, like Atom, 
Visual Studio, or Vim.

The problem of what you propose is that, even if it were possible (AFAIU 
it isn't, given Emacs' key binding conventions), it would be a very 
limited solution: there are only 26 keys reserved for users.  Okay, 52, if 
you count capital letters.

It's what most users expect.  apt install elpa-magit, C-x g, and voilà: 
Magit works.  BTW, Emacs already does "behind-your-back" customizations, 
and doesn't ask you any questions for them.  It provides sensible 
defaults, which work in most cases, and which you can change if need be.
