Well, is says that the website itself was build by the tool. Non-semantic tags, divs instead of links, buttons instead of links, a lot of inline styles (which is a bad practice), deep nesting. So inline styles will make caching css impossible, so high load times, not good for performance. Deep nesting makes the problem even worse. So the result is a slow bloated inaccessible code, but the result may look ok. If all you want is a pretty picture - than yeah, it is a great tool.

I prefer this approach - https://github.com/seek-oss/playroom Just create your components and add them to the sandbox and allow your designers to play with them.
