Please don't use this. -apple-system & BlinkMacSystemFont are OK but after that it's just a scattershot list of guesses that will often be wrong. I have most of the fonts in this stack installed on my Linux desktop for various reasons and none of them are the system font. Just fall back to sans-serif for now and adopt future -apple-system equivalents as they become available.

What do you mean? If it's wrong, the font ain't there. If the font is there, it's the correct font (according to the desire of the one who made the stack). If my stack has "Liberation Sans", it means that if your system has Liberation Sans, then it's going to be used. And it's very often better than the default system font ("Deja Vu Sans", for example, is a typical fallback on Linux and sucks big times compared to Liberation Sans and compared to many other sans-serif fonts).

The way I see it that's the entire point of these "scattershot list of guesses": you can put several, it absolutely doesn't matter. The goal is to find one that matches before falling back to the default.

People can manually install these fonts for whatever reason (I have some for my Photoshop use) while don't want them as the "system font" (because they're not for their OS).

This is not about literally displaying the system font, but about displaying a reasonably appealing font that is already installed. I could not possibly care less about whatever questionable system choice for sans serif some random Linux user makes.
