One of the American magazines I once read regularly, it may have been
Modern Photography, used to publish t-stops as well as f-stops in lens
reviews. I recall there being differences although I do not recall how
large they were. At any event, no reviews present such info any more, I
am sure because the differences have gotten minuscule with just about
modern coated lenses, as you note.
