Have you ever tried to self-host a font from Google fonts? I have. It's actually quite a lot of work. It doesn't just give you a blob of CSS that links to a font file. It dynamically populates the contents based on what Google thinks of your request. You can't just examine your browser network logs to get the content you need. You have to synthesize the contents of a lot of different requests to fully populate the CSS, and get a bunch of different font files. And it's not just combining things blindly, you have to work around all the weird splitting it does to attempt to optimize common cases.

Writing a tool to do all that work for you is the hacker spirit. Mocking the work is not.
