More font sizes by point as in Firefox & Chrome
Introduce font sizes by point size as in Firefox & Google Chrome (eg, 9, 10, 11 etc.)

Point sizes are for printed material. Sure, browsers will use point sizes for webfonts if specified, but web-based sizing should be used for webfonts (em, %, px).
Even vw or vh may be used in the odd case that you want your text to shrink along with the viewport size.
