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

> 1. [`css-fonts-4 font-optical-sizing`](https://www.w3.org/TR//#font-optical-sizing-def)` should be reviewed and checked for consistency with the updated axis description.

Those 2 values (absolute and relative) do seem very useful and desirable to me; but then how to distinguish the 3 kinds - is 14 absolute or relative or a ratio (as proposed at the top of this thread)? 

Eg, Maybe ignorant here but AFAIK there is not (yet) a ratio expression already in CSS; so perhaps there should be several properties?

* `font-optical-sizing`
* `font-optical-sizing-value`
* `font-optical-sizing-relative`
* `font-optical-sizing-ratio`
