Not the author, but last time I checked (3y ago), the fonts CDN was surprisingly slow, like hundreds of milliseconds of latency.
As the website I was optimizing was selfhosted, also selfhosting the font had a noticeable effect on the page load time. See https://github.com/SmilyOrg/photofield/commit/12352667c01624...
I'm not sure what you mean with the rest of the comment though, it's a very small change and it gets cached by the browser like other static assets, so I'm not sure what is the overkill here.
