This is like saying design is a solved problem.

There are a lot of very strong opinions on relatively minor variances. I really like this font, but apparently it isn't nearly as complete as some alternatives.

I've tended towards fonts that I just find readable at the relatively small sizes most sites tend to use. I like Roboto a lot, I like this slightly more... I'm not as big on the Libre Franklin it's also being compared to. It's really personal and some people care more or less than others depending on their needs, and even visibility concerns.
