This isn't restricted to an open-source CMS; any popular CMS gives you this. SharePoint is the gold standard in DIY CMS platforms, and everything you mention above is doubly true of SharePoint. It's certainly easier to find a SharePoint developer than a Drupal developer. I mean, there are downsides to SharePoint: it's commercial software and there's more friction than with Drupal. But I'm not even sure how relevant that is anymore in today's IaaS hosted world -- I can go on Azure and deploy a Sharepoint server in 5 minutes from an image and the licensing costs are baked in. But you're right about developers not valuing these -- CMSes are for established businesses that need a technology platform to manage their messaging across multiple channels. If you consider yourself a product hacker, then something like a CMS isn't likely to be interesting to you.
