If memory serves, pixel-based font sizes were an issue in some browsers
(esp. "the browser of Christmas past") that could only enlarge content
through a "resize text" function that treated pixels as an absolute unit
and therefore did not resize text with a pixel-based size. Later, many
browsers introduced zooming, which also worked for text with pixel-based
sizes. For example, Internet Explorer 9 did (does?) not resize text size
in pixels, but zooming works perfectly well:

SC 1.4.4 does not say it cannot be met through zooming.

Best regards,
