Re: [csswg-drafts] Font optical size multiplication factor (#13331)

Can you explain in more detail how [`optical-sizing: auto`](https://drafts.csswg.org/css-fonts/#font-optical-sizing-def) does not achieve what you are expecting? 

In the majority of cases, the typeface designer and font technician will know better than the style author how `opsz` should be applied, so leaving this to a simple opt-in sounds like a reasonable choice for CSS to make.
