It's interesting to see people rediscover this idea of "develop locally, push static site to web," but I think the weirdest thing for me is, why was this not a continuous thing? Broadly, this looks good for a blog format, but not sure if that's what people need? Anyway, for those interested, I just use http://zim-wiki.org plus a custom CSS template I did.
Because we wanted Dynamic webpage back then. Or at least dynamically generated webpage when something is updated, like links and comments ( When every site was still hosting their own comment sections ). Develop Locally and push Static Site to web may work on Web pages, but doesn't really work for website with some traffic or what we called blog today.
Especially when we were on HDD and single core CPU, updating a few hundred pages takes quite a bit of time. Before uploading tens of Megabytes of Data that takes hours on 56K or ISDN. Compared to being hosted on the web where everything was a press of a button.
Now we are on SSD, where our IOPS is anywhere from 100x to 1000x faster. Even updating sites like Tomshardware or Anandtech should only take seconds. We have Gigabit Internet, uploading should no longer be a problem.
I think vast majority of web site could simply be Static pages, with a small dose of javascript. And may be in the future you could even install your CMS on iPad or iPhone. There is no need to worry about anther Tumblr or Geocities taking down all your content. Your content will stay on your device, and possibly with some sort of Cloud Data Backup. ( iCloud or Google Drive )
This is actually something I keep talking about since ~2017. ( I cant believe that is 5 years already ) So I am glad we are finally moving in that direction.
