Wordpress would have benefited from this. What a lot of webmasters want is, test the site locally, then merge it back. A lot of people turned to Jekyll or Hugo for the very reason that it can be checked into git, and git is reliable. A static website can’t get hacked, whereas anyone who has been burnt with Wordpress security fail knows they’d prefer a static site. And even more: People would like to pass the new webs…
In other words, by itself Dolt couldn’t solve the problem of Wordpress not being run mostly from static assets on a server (plus an API).
