Even for a certain level of collaboration, I think one could get away with using static sites. I haven't tried this in practice but imagine having a git-based CI/CD flow for a static site, where non-technical end users could use the web-based Markdown editors of github.com or gitlab.com to make small changes, save and push via a pull request.
Each merge is of course approved by a more technical user.
I would love to hear if anyone has tried this model.
