This is not a CSS framework, this is a stylesheet you import when you don’t want to think about CSS or styling but want a site that looks alright.

Yes this is exactly the goal of this project

Some people aren't specialized in front-end (or they just find it boring) so they're more the target audience. I did this because I wanted to avoid having to redo an UI each time I started a new hobby project

While there are customization options, it's really intended as just being an include without the need of changing anything else in your documents

A lot of CSS is about art and aesthetics. CSS work will never be "done". There will always be new stylesheets and "frameworks" as long as artists want to express themselves in the medium of the web.
