But when most authors use ems, they still define the root font-size in pixels, and then use ems to increase or decrease it as necessary. That root font-size would be much better off with truemm. I doubt that, in general. If someone defines the root font-size in truemm, and UAs honour that dimension, is it likely that the content will display satisfactorily for users on both an iPhone and a 30-inch desktop display? (Yes, this has all been discussed to death in previous threads.) ISTM that very few "normal" web authors - as opposed to in-house designers of device UIs, or book designers creating a specific physical artifact of known size - should ever have occasion to use "true" units.
