I actually came across this yesterday and set it as a system font on my Linux machine, which runs Elementary.
Although I don't have a HIDPI display, it is nicer and (subjectively) more readable than what I've tried before (I still use Fira Code for coding and Fira Mono inside the terminal, but for the UI tried various variations of Fira, Roboto and other sans serif fonts, yet none of them stuck).
