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.
