Interesting. We've been working on solving the Drupal editing experience "issue" for some time (and a number of other challenges that agencies face). www.cohesiondx.com is a module/web service that already delivers a powerful editing experience plus the ability to create components, styles, templates, layouts etc through a visual interface (I.e Low-code so can be easily adopted). Its a different approach and a commercial product but you can see what can be achieved in Drupal.
