There’s no logic in any of that. CSS and HTML component testing is just automating the designer/dev hand off. You can’t make a functional app with it. And it’s not appropiate as a content editor so doesn’t even rise to the WYSIWYG abilities of something like Wordpress Gutenberg full-site editing or Squarespace.
Ah yes I forgot. That was very slightly before my time in the industry. Remember playing around with komposer in college.
That said Penpot can’t even create links or do any sort of routing. It’s not spitting out html and css. It’s spitting out specs that devs can use as reference when coding. PowerPoint is a more robust wysiwyg than penpot by a basic functionality measure.
