I don't agree. I think the sun in the sky is what people actually care about, and the astronomical details are irrelevant for practical purposes. Civil time needs to be within a couple of hours of local solar time. The differences between mean solar time and apparent solar time are too small to matter - in fact the variation of sunrise matters much more than the variation of midday.
