Consensus & Standardization

After a feature ships in Chrome, the values listed here are not guaranteed to be up to date.



Safari and Firefox shipped the old name, "-apple-system" on Mac, and has a bug to rename and support other platforms, but that has not been done yet. Blink has shipped non-standard name, "BlinkMacSystemFont" again only on Mac. This feature supports the standardized name on all platforms, includes aliasing old name on Mac and measure the usage for deprecation.
