In every experience I've had, non-technical people have had a terrible time doing customizations. Not a single time have I ever seen them successfully navigate customizing pages without someone else stepping in. I see this as the worst case scenario: non-technical people can't do it and technical people also can't because they only have subpar tools to do so. I disagree wholeheartedly with this assumption.

Same. Or maybe something using PHP just as a basic templating engine (like how people used to use it). Something that can be copy/pasted to a dime a dozen cPanel powered shared webhost at a moment's notice.
