This is cool, I didn't actually know you could configure Readline so the title is apt for me :D
Much like in the article I'm also a Vim user who excited to try Vim mode at the command line and I almost instantly hated it. I suppose it's almost required to mention tpope's rsi.vim[0] which gives you Readline bindings in insert and command modes. I've adopted Readline everywhere in my OS except in Vim normal mode which I believe is not too uncommon for many folks.
