System font stacks are great what I’d like more are similar “magic” values to system-ui that provide reasonably metrics-matched local fonts. The biggest reason I use system font stacks is not as much to look native as it is to try to have similar text metrics across platforms without the overhead and quirks brought by webfonts. The system font does bring some advantages though, like on macOS/iOS where that font is San Francisco, it’s designed specifically to look good and read well on screen. Under WebKit you even get hand-tweaked letterforms, metrics, and kerning for different combos of size, weight, and context (title, subtitle, body, etc). Something that would be really cool is if all browsers did what Apple is doing with San Francisco by shipping with a FOSS screen-oriented font like Inter UI[0].
