"Developers merely need to run the npx wp-block-builder command to kick start the process."

On the one hand... great! On the other... it's still not simple enough for me and other part-time hobbyists. It's probably not a fair comparison but I had a look at Amazon's blueprints. If there was a site where I could upload a working php script that could then be wrapped with the necessary code and returned as a zipped set of files I could unzip and install as a block/plugin... when FSE comes in and widgets and similar go the way of the Dodo, such a thing would be a Godsend.
