@Strombo It is not greater than the effort to update one client's site, but if I want to scale this as a business, I can't do everything myself.
Also TMI but I have mental health issues where I go thru periods of being unavailable / unable to work on various tasks, and clients should be able to update their websites when I cannot.
Finally, if I can solve this, I could help static sites become more popular, which could help reduce the environmental impact of the Web. https://solar.lowtechmagazine.com/about/the-solar-website/
