I would think there's room for some middle ground, like DO, but with more sophisticated self service tools to deploy popular software, install OS patches, and so on. Tools that work for non technical people.
Yes, at a higher level, dumbed down installers with reasonable default settings. Deploying whatever applications are popular at shared hosts, like Wordpress, Drupal, Magento, BBS software, and so forth.
And providing some equivalent to Cpanel for things like OS patches, domain management, SSL certificate management, automated backups, web analytics, file manager, etc. Cpanel's license costs are pretty high...they charge per customer / per month, and so it sets a minimum bar for what you can charge.
If you incorporated additional functionality, you could capture more of the market. What wix.com does, for example.
