I've been maintaining my personal website as plain HTML for five years now. I must say, I quite like this method. There's no substitute for practice when it comes to maintaining your skills at editing HTML and CSS.
Yes, you must copy and paste content and not having layout page is annoying at times. But the overhead of just doing it yourself is surprisingly small in terms of the time commitment.
Typically, I'll draft a post in MS Word then open the git repo for my site, hosted on github pages, duplicate and rename the template.html page that includes the CSS, footer, and header for my site and then copy my content into it. When I'm happy with everything, I'll make my commit and then a minute later it's live at my custom domain. Seeing that it takes only 11KBs and 26ms to load my landing page strangely delightful.
