If a designer wants something “just so”, they would have included a @font-face. This sort of font stack is usually mislabeled something along the lines of “system font” (hence it just being labeled sans-serif unlike the specific font face fallbacks). Instead we see a cascade of ‘find something that looks a bit Grotesk per platform’ which may not be the type of sans serif the user wants. And that’s the problem: if you wanted a system font, just ask the system.

I actually don’t mind something designed with purpose & has a reasonable font stack to match it, but this stack isn’t that.
