Or just hire people for your marketing team that have even a passing familiarity with web dev? They're not even that hard to find.

Keep those initial hires aboard and train up the rest. Get rid of the ones who don't want to learn. I mean really why do we try so hard to avoid bridging such simple knowledge gaps? It's not a big deal and we shouldn't shut people out of career development under all these obviously false excuses.

You are forgetting that the websites/CMS is often tool for the organization. It's not just about publishing the content. CMSes are used for writing and editing. Event spaces use their website for planning, chefs use it to generate printed menus.

Static site generators are good for some usecases but too little or too niche for most cases.
