Re: [csswg-drafts] [css-fonts] `system-ui` behavior is undesired for some users (#3658)

I guess we need to solve this when we add more system font families.

I’m afraid I don’t understand what you’re suggesting. Can you please expand? I agree 1 is true. I’m not sure what 2 means, and I’m not sure what you suggest from these two.

One of the original motivations of `system-ui` is to deprecate non-standard vendor-specific values (`-apple-system` and `BlinkMacSystemFont`) and we thought what the [spec](https://drafts.csswg.org/css-fonts-4/#system-ui-def) currently defines can help it:
> This generic font family lets text render with the default user interface font on the platform on which the UA is running.

However, github, medium, bootstrap, and wikipedia considered that this definition isn’t what they want for Chinese Windows, and that they’re back to the vendor-specific values because they provide what they want. True that this is Windows specific problem, but if people stops using `system-ui` and stick to non-standard values due to the problem, isn’t it our failure?

Blink can fix this. I’m hoping to solve this somehow, make `system-ui` usable, and deprecate our vendor-specific value. But 1) I wanted to note that it will no longer “the default UI fonts on the platform” in some cases, and 2) I would like to sync with other browsers on Windows. /cc @atanassov @emilio
