Re: [csswg-drafts] [css-fonts] Proposal to extend CSS font-optical-sizing (#4430)

> My suggestion would be to add two keywords, `px` and `pt` to `font-optical-sizing`

This is fundamentally an incorrect design. `font-optical-sizing: auto` means "set it to whatever it needs to be to get good typography" which will end up being different values on different operating systems. For the same CSS content, browsers on different operating systems should set `opsz` to different values in order to match the coordinate systems of those operating systems. Having the spec say specifically "use `px`" or "use `pt`" will be wrong on half the OSes.
